"Merge" aptly describes the nearly telepathic interplay between these three European Free Improv masters -- Alexander von Schlippenbach on piano, Frank Paul Schubert on alto & soprano saxophones, and Martin Blume on drums -- recorded live in 2019 at Ruhr Jazz Fest, in Bochum, Germany, for an expansive 47 minute improvisation and a brief "Forgin the Work" conclusion.

Since 2009 the UK & European ea-improvising quartet Speak Easy with two remarkable vocalists, Phil Minton and Ute Wasserman (also on birdcall whistles), Thomas Lehn on analog synthesizer and Martin Blume on drums & percussion, have startled and amazed listeners, as heard here in this extended performance at the 2016 Festival Konfrontationen in Nickelsdorf.

A great example of collective free improvisation from the quartet of drummer/percussionist Martin Blue, tenor saxophonist and clarinetist Tobias Delius, pianist Achim Kaufmann, and double bassist Dieter Manderscheid, performing live at the LOFT in Cologne, Germnay in 2016 for two extended intricate, melodic, and commanding performances of expressive and passionate free jazz.

Excellent free improvisation from the quartet of Els Vandeweyer (vibraphone), Fred Van Hove (piano / accordion), Paul Lovens (percussion), Martin Blume (percussion) recording at Kunstencentrum BELGIE & Cultuurplatform Motives for Jazz.

The Triple D Trio of Aurora Josephson (voice), Jacob Lindsay (clarinet) & Damon Smith (bass) met with visiting European improvisers Philipp Wachsmann (violin) and Martin Blume (drums) to record these live concerts in Oakland and SF.

Formed in 2008 Speak Easy brings free vocal improvisers Ute Wassermann and Phil Minton together with drummer Martin Blume and synth player Thomas Lehn for 5 tracks recorded in concert.
