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.

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.

A live concert of Fields' Quite Large Orchestra (aka Multiple Joyce Orchestra) with Frank Gratkowski, Christina Fuchs, Thomas Lehn, Carl Hubsch, &c. &c. performing modular compositions for improvising chamber group, plus an homage to Merzbow.

Since 2002 this large ensemble electric supergroup or "freakestra" has performed uncompromising free improvisation that draws on the best of modern approaches in a staggering display of style and technique.

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.
