Continuing NoBusiness' series of historic loft concerts at Sam Rivers' Studio Rivbea, alto saxophonist Jimmy Lyons leads a quintet featuring bassoonist Karen Borca, bassist Hayes Burnett, and drummers Henry Letcher and Syd Smart in two electrifying 1970s performances, delivering fervent free jazz marked by intricate interplay and dynamic improvisation.

Free jazz bassoonist Karen Borca, a former student of Cecil Taylor, reunites with drummer and percussionist Paul Murphy, both longtime collaborators in saxophonist Jimmy Lyons' band, here distilled as a duo, performing seven studio-recorded dialogs in Virginia -- each an expressive and articulate example of their remarkable technical skill and creativity.

A vital member of groups led by Jimmy Lyons, Bill Dixon, Cecil Taylor, Joe Morris and William Parker, bassoonist Karen Borca is heard in two Vision Festival performances under her own name performing her own compositions in trio, quartet and quintet formations with luminaries Rob Brown, William Parker, Reggie Nicholson, Susie Ibarra, Todd Nicholson, Paul Murphy and Newman Taylor-Baker.

A truly wild concert of free jazz from Cecil Taylor's transatlantic orchestra, captured live at the 1984 Jazz Jamboree in Warsaw, Poland, bringing together impressive improvisers from the US--William Parker, John Tchicai, Jimmy Lyons, Karen Borca, Frank Wright, & Henry Martinez--with European Free Jazz leaders Tomasz Stank, Enrico Rava, Conrd Bauer & Günter Hampel.

Originally issued on the Hat Hut label as a 3-LP set, this 1978 recording of Cecil Taylor compatriot, saxophonist Jimmy Lyons, performing live at Collective for Living Cinema in New York in a unique band with Karen Borca (bassoon), Munner Bernard Fennel (cello) and Roger Blank (drums).
