And finally a CD of this fantastic CT quintet has been given to the friendly listener by Fundacja Sluchaj.
CT with Tristan Honsinger, Teppo Hauta-aho, Harri Sjöström and Paul Lovens recorded in 1998 at Tampere Jazz Happening, Finland.
Then we have a collaboration of Roscoe Mitchell with three Polish musicians which is available since November 2020 from Bocian Records.
The only musician I knew before was - apart from RM - the reed player Jerzy Mazzoll whom I remember from some concerts with Peter Brötzmann.
Two more RM are due for release or already available (not listened yet nor did I found a source for obtaining.
