The Emerald Duets is a crowning achievement among Wadada Leo Smith's many recorded duo collaborations with drummers/percussionists, that have previously featured such creative giants as Ed Blackwell, Jack DeJohnette, Milford Graves, Louis Moholo-Moholo and Gunter Sommer, among others. The Emerald Duets features four master drummers who have each, in their own unique fashion, contributed to the way modern drumming has developed in the past six decades and how it is now perceived. Pheeroan akLaff, Andrew Cyrille and Han Bennink are each featured on one disc and Jack DeJohnette on two discs, including Smith's five-part composition "Paradise: The Gardens and Fountains" that fills the fifth disc of this boxed set in its entirety.

2 Blues For Cecil features three legends of modern improvised music, trumpeter Enrico Rava, bassist William Parker and drummer Andrew Cyrille. Rava and Cyrille are among the elders of improvised music with their careers going back to the 1960s whereas Parker rose to prominence during New York's loft jazz era of the 1970s. The three musicians share one major link in their respective careers. Namely, they all have, at various times, been members of Unit or other ensembles of another legend, the late pianist Cecil Taylor. Enrico Rava, William Parker and Andrew Cyrille first performed together as a trio in tribute to Cecil Taylor, with Taylor himself present, at the Whitney museum in April 2016 as part of an exhibit/program under the heading "Open Plan: Cecil Taylor." 2 Blues For Cecil was recorded on February 1 and 2 at Studio Ferber in Paris following the trio's concert on December 31, 2020 under the heading "Tribute to Cecil Taylor" as part of the Sons D'Hiver festival in Paris.

The new album from the quartet led by one of jazz’s innovators, drummer Andrew Cyrille, carries the story forward from the 2016 release The Declaration of Musical Independence, a recording which Down Beat hailed as “an unabashed exploration into time, pulse space and atmosphere…ambitious yet simple, rich yet stripped-down, challenging yet infinitely satisfying.” Bill Frisell and Ben Street remain from the Declaration line-up with David Virelles taking the piano role. Each of the players has space for improvisational expression – and Frisell and Virelles also contribute material - but it is Cyrille’s communicative sensibility and what the New York Times called his “watchful, flowing pulse” that guides the band.

Andrew Cyrille’s title Lebroba is a contraction of Leland, Brooklyn and Baltimore, birthplaces of the protagonists of an album bringing together three of creative music’s independent thinkers. Each of them made his first ECM appearance long ago: drummer Andrew Cyrille on Marion Brown’s Afternoon of a Georgia Faun (1970), trumpeter Wadada Leo Smith on his own classic Divine Love (1978), and guitarist Bill Frisell on Eberhard Weber’s Fluid Rustle (1979); these are, of course, players of enduring influence. Frisell contributed to Cyrille’s previous ECM disc The Declaration of Musical Independence, but Lebroba marks a first-time meeting for the guitarist and Wadada Leo Smith. A generous leader, Cyrille gives plenty of room to his cohorts, and all three musicians bring in compositions, with “Turiya”, Wadada’s elegant dedication to Alice Coltrane, unfurling slowly over its 17-minute duration. In his own pieces, including the title track and the closing “Pretty Beauty”, Cyrille rarely puts the focus on the drums, preferring to play melodically and interactively, sensitive to pitch and to space.
