Mats Gustafsson, born in Umeå in 1964, is a Swedish saxophonist, improviser and composer whose baritone and tenor playing has the force of a rock band. He leads or co-leads The Thing, Fire!, Gush, Sonore, Swedish Azz and the NU Ensemble, has played in Peter Brötzmann's Chicago Tentet and Barry Guy's New Orchestra, and has worked with Sonic Youth, Merzbow, Jim O'Rourke, Otomo Yoshihide, Yoshimi and Ken Vandermark. Eighteen hundred concerts and more than two hundred records across Europe, Australia, Africa, the Americas and Asia have made him one of the busiest figures in free music, and a collector and advocate of its history through his writing, his label work and the Discaholic Corner website, where he trades records and interviews his heroes.
