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.

To celebrate drummer/percussionist Eddie Prévost's 80th birthday, Café Oto hosted four concerts once a week in June, 2022, each a differing configuration from Prévost's history; this final concert reconvened for an extended improvisation between Prévost & guitarist Keith Rowe, with a "Postscript" from pianist John Tilbury recorded at his home in January, 2023.

There is uncertainty of when pianist John Tilbury recorded these three solo keyboard works by his associate and friend, legendary minimalist composer Terry Riley, performing "Keyboard Study #1" and #2, along with "Dorian Reeds" using piano, electric organ, harpsichord & celesta, captured with excellent quality in superb performances from Tilbury at the height of his powers.

Their first release in 2000 performing Cornelius Cardew's "Treatise", for 20 years the Formanex quartet of sound artists, conceptualists and experimenters Anthony Taillard, Christophe Havard, Emmanuel Leduc, and Julien Ottavi are heard here in collaborations with Keith Rowe, Kasper T. Toeplitz, Ralf Wehowsky, Seth Cluett, Michael Pisaro, Radu Malfatti, &c.

Recorded live at the Huddersfield Festival of Contemporary Music in 2006, this is the 3rd and final volume of works by Morton Feldman performed by the Smith Quartet with John Tilbury on piano, recorded in high quality DVD audio and with extensive liner notes by Tilbury.

Recorded at the festival Neposlusno (Sound Disobedience) in Ljubljana, Slovenia in 2012, the AMM duo of Eddie Prevost on percussion and John Tilbury on piano perform an extend improvisation of tension and dynamic, delicately balancing sound in a rich dialog.

"Two Pianos" is one of Morton Feldman's most experimental and radical works, performed here by John Tilbury & Philip Thomas; plus lesser known works including 'Piece for Four Pianos', 'Between Categories', 'False Relationships and the Extended Ending' and 'Two Pieces for Three Pianos'.

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.

The 2nd volume of "Music for Piano and Strings" by Morton Feldman is performed by The Smith Quartet with John Tilbury, presenting "Patterns In a Chromatic Field", and "Piano, violin, Viola, Cello", on DVD audio to allow for the length of these large works.
