An exact contemporary of Haydn, Franz Ignaz Beck (1734-1809) was a pupil of Stamitz in Mannheim, but lived and worked mainly in Bordeaux, where he was rated highly. Documented information about Beck is meagre and the 3-page introduction is unable to date this Stabat Mater, which is reckoned his masterpiece. It failed initially at Versailles and caused something of a furore, because of his forward looking harmonic modulations; the orchestra sabotaged his instructions for extreme dynamic contrasts. It points towards Berlioz in its originalty and I fully endorse the commentator's claim that Beck is another neglected composer whose music, once heard, demonstrates, yet again, that the accepted canon of 'great' composers, with most of the others cast into oblivion, is misleading and regrettable.

One might be forgiven for thinking Beatles Baroque III by Les Boréades would actually sound Baroque, as it and two previous volumes are billed, but such is not the case. Even though this Canadian early music ensemble has impressive credentials, and plays the repertoire from Frescobaldi to C.P.E. Bach with aplomb, its performances on this disc are overwhelmingly modern in feeling and not too far removed from the actual music produced by the Beatles and George Martin in the 1960s.

Keb' Mo''s self-titled first album, from its Robert Johnson covers to its appearance on a resuscitated Okeh Records, seemed to suggest the arrival of a Delta blues traditionalist, even though the former Kevin Moore was really a Los Angeles native who had kicked around the music business for years playing various styles of music. The follow-up, Just Like You, was therefore a disappointment to blues purists, since it clearly used folk-blues as a basis to create adult contemporary pop in the Bonnie Raitt mold. But to the music industry, that was just fine, since it fostered the hope that here was an artist (finally!) who could find a way to make the blues - consistently revered but commercially dicey - pay, and Keb' Mo' won a Best Contemporary Blues Album Grammy for his effort. Slow Down (1998) brought him a second Grammy…

Black metal with the happiest keyboards the genre has ever seen, yet still uncompromisingly brutal. "Children of Decadence" could be Emerson, Lake & Palmer, for the love of Beelzebub; such is the level of complexity and prominence of synthesizers. The frightening Finnish fivesome does a nice job of mixing up tempos on this, the band's third studio disc, and manages to keep up the intensity in spite of (or maybe because of) the aural auditory mood swings. You won't even recognize the bonus track cover "Hellion," and it doesn't even matter.

Right down to the hip, pleasant cover model, Buscemi's second album of groovy productions is a near-perfect match for his debut, 1998's Mocha Supremo. Producer Dirk Swartenbroekx flaunts his love of breezy, continental rhythms and late-night atmosphere. Though the scattered Latin-dance fusions bossa nova meets disco, salsa meets drum'n'bass, samba meets downtempo house aren't exactly pioneering ideas, Swartenbroekx is an able hand who knows when and how to freshen what could be a stale production.

Founded in Montreal in 1993, Quasar is a saxophone quartet devoted mainly to new music, and particularly to the creation and promotion of Canadian works. This disc presents an exciting selection of works, most of which were commissioned and premiered by Quasar.

Lobgesang, Mendelssohn's ''Hymn of Praise'', is no longer a rarity on disc, with a dozen versions listed. That makes it timely that Spering, following up the success of Herreweghe's Harmonia Mundi version of Elijah (4/94), here presents a performance in period style. When the composer's preference for fast speeds is well documented, and has so convincingly been followed up by his latterday successor at the Leipzig Gewandhaus, Kurt Masur, it is perhaps surprising that Spering is far more relaxed in his choice of tempos. His overall timing—64'48'' as against Masur's 58'32''—shows what a wide discrepancy there is, and in no way does he let the music drag or become sentimental. For with clean, crisp textures this is a most refreshing performance, full of incidental beauties, of a work that for several generations was regarded as too sweet on the one hand, over-inflated on the other. Spering's clean directness and his obvious affection for the music reverses that jaundiced judgement.

Copland wrote Billy the Kid in 1938 on commission from Lincoln Kirstein, a noted New York impresario and cofounder of the New York City Ballet. The music became an instant success, incorporating as it does several well-known folk and Western tunes and telling an episodic story more about the Wild West in general than specifically about the notorious outlaw William H. Bonney (born Henry McCartney).

People will buy this disc primarily for the Seasons, not the free sampler disc, so all I will say about the latter is that it will allow you to hear short excerpts from other discs in OPUS 111 catalogue, celebrating 1000 years of Russian Music. The excerpts include instrumental, choral and orchestral pieces, all of which appear to be complete.

Annette Peacock has been a defining influence on the music of ECM for many years, but An Acrobat's Heart is the first album she has made for the label as a leader. Here Peacock turns away from her previous work with electronic elements to produce a spare, ethereal set of compositions for voice, piano, and strings echoing the style of her early '80s album Skyskating. An Acrobat's Heart also marks the first time that Peacock has composed for strings, and the Cikada String Quartet's seamless accompaniment almost breathes with her.

The Secret Language of Birds is Ian Anderson's third solo album, but the first to specifically highlight his melodic skill and guitar prowess on a set of folk-inspired songs. His first solo album, 1983's Walk into Light, was marred by its full embrace of sterile '80s production in lieu of rusticity. While his second effort, 1995's Divinities, was a move in the right direction and a sonic precursor to the set at hand, it still was held back by its conscious decision to downplay Anderson's obvious acoustic heritage for a more classical bent. But sometimes the obvious is what works best, and Jethro Tull fans were pleased to learn that Anderson's third release finally embraced his classic sound. Just like Tull's excellent Roots to Branches, this one has a decided ethnic flair, running the gamut from Indian to Russian to Celtic.

Return of Saturn is an almost defiantly mature record about two things: Stefani's exploration of a troubled romance and her own romantic ideals, plus a serious attempt by the group to not only keep new wave alive, but to make that adolescent music relevant to an older audience. It's a high concept, but Return of Saturn is filled with satisfying contradictions. It's melodic, but deceptively complex; it can seem frothy, but it's never frivolous. No Doubt's desire to expand the emotional template of new wave is the perfect match for Stefani's themes – she may be writing about love, but she's not writing adolescent love songs. Fragments of her teenaged romantic fantasies remain, but she's writing as a woman in her late 20s. She's tired of being another "ex-girlfriend" – she wants to fall in love, get married, and have a family. It's a subject that's surprisingly uncommon in pop music, which would alone make Return of Saturn an interesting album. What makes it a successful one is that the band delivers an aural equivalent of Stefani's lyrical themes.

A remarkable vignette of artificial 17th-century Italian courtly life. ‘Love’ is hunted in eyes, in hair, between breasts, before a hilarious game of ‘tongue-twisters’. Best though are 14 mannered mood-pictures spanning every emotion in intensely detailed word-painting. Truly revelatory.

Houston native Jay Hooks can stand shoulder to shoulder with the long list of Texas electric blues guitar legends he emulates. He grew up playing guitar on the Houston bar circuit throughout the late '70s and '80s, earning his stripes by playing in the shadow of local legends like Albert Collins and Billy Gibbons. Taking a nod from these sources, Hooks' was able to incorporate the highly typified electric blues/rock sound of Stevie Ray Vaughan with his affinity for more traditional blues influences. He received his first major exposure after he was asked to join Texas R&B die-hard "Miss" Lavelle White on a series of national tours.
