Roman philosopher Titus Lucretius Carus named "Clinamen" the unpredictable (in time and space) swerve of atoms falling in the void, which aptly describes the unexpected directions taken in subtle free improvisation from this French trio, led by bassist Louis-Michel Marion, with Jacques Di Donato on clarinet, and Philippe Berger on viola.

IST, configured as the duo of double bassist Simon H. Fell and cellist/percussionist Mark Wastell, performing a virtual quartet at London's Cafe OTO, using using pre-recorded fragments of solo work from late guitarist Derek Bailey and tap dancer Will Gaines, combined with sections of silence of unforeseeable length, and then combined with the live musicians; amazing.

An epic journey in free vocal improvised music from the trio of vocalist Anna Gadt with Zbigniew Chojnacki on accordion & live electronics and Krzysztof Gradziuk on drums, performing live in the studio in Nieport, Poland, with arrangements, deconstructions and original music by Anna Gadt, along with the theme from "Monumentum pro Gesualdo" by Igor Stravinski.

Reissuing the 2005 Utech release from the duo of Frode Gjerstad on clarinets and Steve Hubback on hand-made drums, cymbals and gong, performing live at Lille Konsertsal, Stavanger, Norway, in February 2001.

The improvising string duo of stalwart London improvisers, Daniel Thompson on acoustic guitar and Phil Durrant on the octave mandola, are heard in two settings of texturally rich, intricate interactions, first at Cafe OTO in 2022 for an extended improvisation, then at Cable Street Studios two months later for six succint, impressively diverse dialogs.

The legendary trio Joseph Holbrooke — guitarist Derek Bailey, bassist Gavin Bryars, and drummer Tony Oxley — reunited after decades for one final performance in 2001, captured in this historic live recording that highlights their uncompromising commitment to free improvisation, the set resonating with both the radical spirit of their 1960s origins and the profound artistry of three pioneering voices in avant-garde music.

Seminal figures in the evolution of free or nonidiomatic improvisation, guitarist Derek Bailey and percussionist/pocket trumpeter John Stevens are heard in a 1989 London performance vividly captured by Michael Gerzon at The Duke of Wellington, their restless and enthusiastic interplay shifting from angular invention to lyrical reflection in a compelling document of their remarkable rapport.
