Since leaving the punk group The Ex in 2003 acoustic bass player Luc Ex has become a force of creative music collaboration and improvisation driven by his punk roots and the Dutch experimental music scene. He worked for many years with the cellist Tom Cora in ‘ROOF’ - A 4tet with vocal virtuoso Phil Minton and drummer Michael Vatcher, which after Tom’s death became 4WALLS with the maverick British pianist Veryan Weston, both groups receiving international acclaim. They were specifically appreciated by their new approach of combining tightly rehearsed pieces with free improvisations. Forming a new group in 2007 with Veryan Weston, Tony Buck, Hannah Marshall, Mandy Drummond and Ingrid Laubrock – SOL 6 saw luc continuing a collaboration with Veryan Weston combining original rhythmically driven pieces with open and highly explosive improvisations. He has recently started to work on a new project TRIOLEX with improvisation maestro’s Tristan Honsinger, Phil Minton and African drummer Serigne CM Gueye, and in Assemblee with saxophonists Ab Baars, Ingrid Laubrock and Chicagoan Drummer Hamid Drake.
