Since co-founding the seminal improv rock outfit Phish in 1983, guitarist, composer, and songwriter Trey Anastasio has explored a wide variety of musical pathways ranging from atonal fugues and elaborate charts with Phish to adventurous free jazz on his first solo project, Surrender to the Air (1996), to collaborations with the likes of Tom Marshall, Les Claypool, Philip Glass, Stewart Copeland, and others. After Phish went on long-term hiatus in late 2000, Anastasio has focused on a myriad of projects, including Oysterhead and his eight-piece solo band.
