Probably the most pop-accessible of Laurie Anderson's recorded work, Mister Heartbreak features a number of stunning luminaries on the cutting edge of popular music at the time. Striking guitar work by King Crimson guitarist Adrian Belew permeates this disc – notably on "Sharkey's Day" – punchy and angular. The production and bass work from Bill Laswell is superb. Peter Gabriel – at the time still coming off the buzz of his departure from Genesis – is featured in a duet with Anderson on "Excellent Birds." There is a heavy reliance on early-'80s synthesizers which would normally be very off-putting, but here they are executed well. Nowhere does the music slip into irreparable '80s cliché; it is still an entertaining listen. Lyrics are typical of Anderson' work – complex, literate, provocative, difficult to fully comprehend. Haunting "Gravity's Angel" borrows imagery from Thomas Pynchon's Gravity's Rainbow. Spoken word delivery on "Sharkey's Night" is given by the legendary William S. Burroughs. This is a very satisfying listen and a great intro for those unfamiliar with Anderson's work.

Overlapping textures and soft, shifting timbres are the most recognizable features of Morton Feldman's music, and his attractive sonorities draw listeners in ways other avant-garde sound structures may not. This music's appeal is also attributable to its gentle ambience, a static, meditative style that Feldman pioneered long before trance music became commonplace. The three works on this disc are among Feldman's richest creations, yet the material in each piece is subtly layered and integrated so well that many details will escape detection on first hearing. In Piano and Orchestra, the piano is treated as one texture among many, receding to the background and blending with muted brass and woodwinds in a wash of colors. Cello and Orchestra might seem like a conventional concerto movement, especially since the cellist is centrally placed on this recording and plays with a rather lyrical tone. However, Feldman's orchestral clusters are dense and interlocked, which suggests that the cello should be less prominent and blend more into the mass of sounds behind it. No such ambiguity exists in the performance of Coptic Light, which Michael Tilson Thomas and the New World Symphony Orchestra play with even dynamics and careful attention to the work's aggregate effect, which is mesmerizing.

Some people would quickly run away from the music of someone who claims to admire the music of Berg, Crumb, and Cage. Franguiz Ali-Zadeh admires all of those composers and uses similar techniques in her composition, but she also finds inspiration in the music of her native Azerbaijan. With all of this, she creates especially evocative, picturesque works that invite listening more than once. Oasis, the opening work on this disc of her music featuring the Kronos Quartet, begins extremely quietly with water droplets, and then the quartet enters with desolate harmonics, depicting the desolation of the desert. Later in the piece, voices of those taking refuge in the oasis are heard. Ali-Zadeh's music is full of sounds beyond that of the traditionally played instruments of the string quartet and the piano, sounds that enhance and become part of the music. Sometimes it is techniques such as pizzicato, harmonics, col legno, or preparing or playing the strings of the piano; other times it is added instruments, as in Mugam Sayagi, or recorded sound, as in Oasis.

With the possible exception of Richard Pinhas' Heldon, Gilbert Artman's Lard Free was probably the premier French progressive group of the '70s. The prolific Heldon might win in terms of amount of material, but the three near-perfect albums by Lard Free (despite the truly wretched band name) probably have them beat in terms of overall quality. Although Artman, a drummer who also dabbles in synthesizers and piano, called Lard Free a group, he was the only constant member; all three albums have different lineups. 1973's Lard Free consists of relatively short pieces with prominent piano and saxophone parts, and as such is the most jazz-oriented of the three. The following year's I'm Around About Midnight consists of three long pieces with much more synthesizer; at times, it sounds almost like early (pre-ambient) Tangerine Dream, or perhaps Clear Light, the French collective Artman and the then-current lineup of Lard Free occasionally worked with around this time. 1977's Lard Free III, also known as Spirale Malax, is Artman's best work, a pair of side-long experiments that combine space music, jazz, and King Crimson-style heavy progressive rock better than many groups (including King Crimson) could ever hope to manage.

What might have been simply seen as an agreeable enough debut album has since become something of a notorious legend because Kraftwerk, or more accurately the core Hütter/Schneider duo at the heart of the band, simply refuses to acknowledge its existence any more. What's clearly missing from Kraftwerk is the predominance of clipped keyboard melodies that later versions of the band would make their own. Instead, Kraftwerk is an exploratory art rock album with psych roots first and foremost, with Conny Plank's brilliant co-production and engineering skills as important as the band performances. Still, Hütter and Schneider play organ and "electric percussion" – Hütter's work on the former can especially be appreciated with the extended opening drone moan of the all-over-the-place "Stratovarius" combined with Schneider's eerie violin work. But it's a different kind of combination and exploration, with the key pop sugar (and vocal work) of later years absent in favor of sudden jump cuts of musique concrète noise and circular jamming as prone to sprawl as it is to tight focus.

This may be the single most powerful piece of music that the Kronos Quartet has ever recorded, and perhaps that Terry Riley has ever written. This is because Requiem for Adam is so personal, so direct, and experiential. Requiem for Adam was written after the death of Kronos violinist David Harrignton's son. He died, in 1995, at the age of 16, from an aneurysm in his coronary artery. Riley, who is very close to the Harringtons and has a son the same age, has delved deep into the experience of death and resurrection, or, at the very least, transmutation. Requiem for Adam is written in three parts, or movements. The first, "Ascending the Heaven Ladder," is based on a four-note pattern that re-harmonizes itself as it moves up the scale. There are many variations and series based on each of these notes and their changing harmonics, and finally a 5/4 dance as it moves to the highest point on the strings. The drone-like effect is stunning when the listener realizes that the drone is changing shape too, ascending the scale, moving ever upward and taking part in the transmutation of harmony.

During the rehearsals for the string quartet version of "White Man Sleeps," a strong artistic bond developed between the work's performers, the renowned Kronos Quartet, and its composer, Kevin Volans. This led Kronos to commission a second-string quartet from Volans, especially written for the musicians. Like "White Man Sleeps," it is a stunning piece of music, recommended to every world music lover who wants to cross the bridge to contemporary, modern music. The work comes in three movements, each one with a different character. Most remarkably are the Ethiopian influences in the beginning bars of the first movement (compare this motive with the vocal style of the distinguished Ethiopian singer Aster Aweke) and the joyous Southern African dance-like motive featuring after the more contemplative opening of the second movement. The slightly melancholic song-like structure of the short third movement draws the work to a close.

This disc is supposed to hurt. Just look at the program: it starts with Crumb's Black Angels for electric string quartet, a work that is the aural equivalent of Coppola's Apocalypse Now, and ends with Shostakovich's String Quartet No. 8, a work that is either the aural equivalent of a monument to the victims of war and fascism written in the ruins of Dresden or the musical equivalent of a suicide note written before the composer joined the Communist Party. With the spooky and evocative performances of Thomas Tallis Spem in Alium, Istvan Marta's Doom. A Sigh, and Charles Ives' There They Are!, this disc is so painful it could be the soundtrack for an unmade Kubrick movie. The question is, is this disc supposed to hurt so much? The Kronos Quartet is a harsh and aggressive ensemble with an angular approach to rhythm and structure and an overwhelming need to assert its individual and collective identity.

Edgar Varèse is regarded as one of the pioneers of New Music, and with good reason. His piece “Ionisation” was the first-ever composition written exclusively for percussion ensemble to be performed in a traditional concert hall setting; and he explored and searched intensely for sonic experiences. Varèse integrated first the world of sounds, then electronic instruments into traditional orchestras, thereby opening a door to a new awareness of listening. His work substantially influenced those generations of composers that came after him: a link between the beautiful, the exciting and the musically unfamiliar. The 2009 Salzburg Festival dedicated its “Kontinente” series to this brilliant New Music pioneer – and we are delighted to present these excellent recordings to you! (Col Legno)

Bruce Brubaker artistic skill and understanding of this music is beyond reproach and will thrill any fan of the collected composers work on this CD. The sound quality is outstanding as well. Bruce Brubaker has recorded two CDs on the Arabesque label in a continuing series exploring modern American piano music. The most recent, Inner Cities, was released in September 2003, and includes Brubaker's transcription of Pat Nixon's aria from Adams's opera, Nixon in China. The previous CD, Glass Cage , with pieces by Glass and Cage, was named one of the ten best releases of 2000 by The New Yorker magazine.
