SUM - Invenio / Ergo

Master drummer and improvisor Eddie Prévost is joined by Ross Lambert on guitar and Seymour Wright on alto, for two long pieces, together more than eighty minutes long. Its open textured approach, and the musicians' listening skills and subtle interaction make this a strong performance." - The Free Jazz Collective  

"One shouldn't approach this record under the influence of an 'AMM MAN PLAYS JAZZ STANDARDS' headline. There's no headline, just a continuation of a long and thoughtful story whose chief premise is the denial of the single expressive self - though Prévost's unaccompanied performances, like the solo tam-tam record entelechy are fascinating documents - in favour of a collective exploration that changes the case of cogito (or invenio) ergo sum to the plural. None of these players would claim to be making a historic document, and one senses in them different kinds of diffidence to the act of making a record in the first place, but in its (mostly) quiet way the recording marks a modest epoch in the evolution of great music." - Brian Morton

Ross Lambert

Northern Irish (and London-based) guitarist and ‘magnetic and vibrating sources’ player Ross Lambert, has in his own words, the following fundamental and simultaneous approaches to live performance: to play as though it was both the first time and also the last; and to able to differentiate between what is good and worth conserving and what is not. Ross has been involved in, initiated and been a connector between a very wide variety of improvisatory music since his first exposure and (immediate) commitment to it, in Sheffield via Derek Bailey during the mid-1980s. Although under-recorded (he claims ‘by choice’), Ross has worked with a huge number of musicians from around the world, including Tetuzi Akiyama, Ami Yoshida, Jean-Luc Guionnet, Paul Hession, Rhodri Davies, John Butcher and Evan Parker, as well as his close friends Eddie Prevost, Seymour Wright, and Sebastian Lexer. 

Eddie Prévost

Eddie Prévost plays with immense fire, grace and invention. Founder of the essential AMM, collaborator of the greatest improvisers internationally, since the 60's he has kept a continuous contact with the scene and always manages to invent anew his contribution to "meta-music".

“Prévost's free drumming flows superbly making use of his formidable technique. It’s as though there has never been an Elvin Jones or Max Roach.” - Melody Maker

“Relentlessly innovative yet full of swing and fire.” – Morning Star

Seymour Wright

Seymour Wright’s work is about the creative, situated friction of learning, ideas, people and the saxophone – music, history and technique ­– actual and potential.

His solo work is documented on three widely-acclaimed collections - Seymour Wright of Derby (2008), Seymour Writes Back (2015) and Is This Right? (2017).

Current projects include: abaria with Ute Kanngiesser; [Ahmed] with Antonin Gerbal, Joel Grip and Pat Thomas; @xcrswx with Crystabel Riley; GUO with Daniel Blumberg; The Experimental Library with Evie Ward; XT with Paul Abbott; a trans-atlantic duet with Anne Guthrie, and, with Jean-luc Guionnet a project addressing an imaginary lacunae in Aby Warburg's Atlas Mnemosyne.

His writing has been published in C//A, Sound American and The Wire.
