Recorded for the release concert of their 2013 album Exta, the trio of John Butcher on saxophones, Thomas Lehn on analog synthesizer and John Tilbury on piano captured this extraordinary live concert at Cafe Oto in London, only the second time the group had performed together, recording in two extended sets but segmented into four exceptional and dramatic improvisations.

After "Exta", where saxophonist John Butcher and electronics artist Thomas Lehn met with pianist John Tilbury, the duo now meet with New York pianist Matthew Shipp for a distinct improvisational entanglement of Butcher's dense streams, Lehn's rich sound floor, and Shipp's thick repetitions.

At the request of Fataka, amplified violinist Angharad Davies and electronic improviser Phil Julian met at Cate OTO in 2014 & 2018, the two exploiting their distinct approaches to free improvisation to perform these evolving works that ebb and flow in almost hallucinatory intensity while exploring the timbral potential of their unique instrumentation.

The mystifying duo of Axel Dorner (trumpet, electronics) and Mark Sanders (drums, percussion) blurs the line between electronic and acoustic in this enthralling album.

Three superb London improvisers, two from the new generation of free improv--bassist John Edwards and drummer Mark Sanders--in a trio with legendary pianist John Tilbury in a two part work of tension and release, performed live at Cafe Oto in 2013.

Two live sets of exemplary improvisation: the first revelatory encounter of pianist Sebastian Lexer and drummer/percussionist Steve Noble from 2011, and a more considered and spacious meeting in 2014, both from London's Cafe OTO.

Drummer Steve Noble assaults his drum kit in a way that excellently parallels Ikue Mori's electronics, producing an enthralling blend of acoustic and electronic music.

A meeting between two accomplished saxophonists recorded live at Kernel Brewery, in London in 2014, and at The Studio in Derby, with Seymour Wright on alto saxophone and Evan Parker on both alto and soprano, criss-crossing and combining in exuberant and astonishing ways.

UK free improvising drummer Roger Turner meets Japanese guitarist Otomo Yoshihide at the Hara Museum, Tokyo in the winter of 2013 for a performance that balances introspective improvisation with assertive and authoritative playing for a captivating and dynamic album.
