Album Description"Anthony Braxton ... remains as prolific, diverse, inspired, and intriguing as ever." -- One Final Note "His music is often playful, with lines shooting out from all angles, and tempos picking up only to slow down." -- New York Times Quartet (GTM) 2006 is Anthony Braxton's first release for Important Records. GTM stands for "Ghost Trance Music," and this four-disc box set contains four Ghost Trance compositions recorded with Anthony Braxton playing reeds, Carl Testa on bass, Aaron Siegal on percussion, and Max Heath on piano. The box also contains a definitive essay by Braxton on his Ghost Trance compositions. Anthony Braxton is an American composer, saxophonist, clarinetist, flautist, pianist, and philosopher. Over the course of his career he has crafted an immense body of highly complex work. Though Braxton is hardly known to the casual listener, he is certainly one of the most prolific American musicians and composers to date, having released well over 100 albums since the 1960s. Early in his career, along with trumpeter Wadada Leo Smith and violinist Leroy Jenkins, Braxton led a trio and was involved with the Association for the Advancement of Creative Musicians. In 1968, Braxton recorded the highly influential For Alto, the first full-length album for unaccompanied saxophone. He joined pianist Chick Corea's existing trio with Dave Holland and Barry Altschul to form the short-lived avant-garde quartet Circle, and when Corea broke up the group Holland and Altschul remained with Braxton for much of the 1970s as part of a quartet, with the rotating brass chair variously filled by trumpeter Kenny Wheeler or trombonists George Lewis or Ray Anderson.
