"Shifa", or "Healing", is the London-based trio of saxophonist Rachel Musson, pianist Pat Thomas, and drummer Mark Sanders, here in a live concert at Cafe Oto in 2018 of two collective improvisations of arching sax lines, rolling and potent drumming, powerful block chords and intricate lines, from dark to joyful moments, an intoxicating tonic for the ears.

Part of Evan Parker's 70th birthday in 2014, this album captures the super-charged quartet of Evan Parker on tenor saxophone, Mikolaj Trzaska on alto sax, bass clarinet, John Edwards on double bass, and Mark Sanders on drums, in two sets for two extended improvisations of both power playing and powerful communication, along with one shorter final statement.

LAST is part of a series by Caroline Kraabel (LIO, Remote Viewers) mixing live improvisation with pre-recorded material provided by Robert Wyatt for this purpose, performed live at Cafe OTO in two versions: first where the 15-piece ensemble has not yet heard the Wyatt interventions, and second where they were familiar with and use his voice to structure what they play.

Two saxophones take the front line in Paul Dunmall's 2018 studio album, the leader on tenor saxophone with fellow tenor player Julian Siegel, also on bass clarinet, while Mark Sanders drums and Percy Pursglove handles bass and also trumpet, as the band falls into a hard bop mode, weaving lines together over wonderfully turbulent and soulful grooves; outstanding.

A studio album between three UK master improvisers -- John Butcher on sax, John Edwards on double bass, and Mark Sanders on drums -- the trio pushing the envelope in technique and dialog in nearly telepathic playing that transports the listener into their environment, as the music builds and releases in effortless ways that are stunning and exulant; highly recommended.

Two extended examples of free improvisation from UK stalwarts, tenor saxophonist Paul Dunmall, bassist John Edwards, and drummer Mark Sanders, joined by New York pianist Matthew Shipp, all captured live at Cafe Oto in 2010; set one is an unflagging example of energetic collective improv, set two more introspective yet vital and demanding; a superb concert!
