Experimentation is like air for Anthony Braxton. In 1969 he made one of the first solo saxophone albums in history, and he's continued to blaze new paths, invigorating the practice two decades later on “138B—African Violets.” He brings fierce energy to Lennie Tristano's hard-swinging “Victory Ball,” while also registering as the first veteran jazz great to collaborate with brashly noisy Wolf Eyes, as he did on “Rationed Rot.”
