In early summer 2011 I was lucky enough to attend Vancouver’s terrific annual jazz festival. One of the most explosive and exciting performances I caught during my visit was recently released commercially: the first-time meeting of saxophonists Colin Stetson and Mats Gustafsson, a collaboration cooked up by the festival’s excellent artistic director, Ken Pickering. The two men engaged in a sanguine battle of brawny horns that’s captured on Stones (Rune Grammofon). Both players are known for their mastery of extended techniques, and though they use them to very different ends, here they manage to find a way to bond and communicate.
