Trey Anastasio (born Ernest Joseph Anastasio III on September 30, 1964) is an American guitarist, composer, and vocalist most noted for his work with the rock band Phish. He is credited by name as composer of 152 Phish original songs, 140 of them as a solo credit, in addition to 41 credits attributed to the band as a whole. He was ranked as number 73 on the Rolling Stone List of the 100 Greatest Guitarists of All Time in 2003.
Anastasio, whose name derives from the Greek word for resurrection, began playing the drums as a youth, turning to guitar while a teenager. His father was an executive with Educational Testing Service. Anastasio's mother Dina, with whom he wrote songs as a child, was an author and the editor of Sesame Street magazine. He attended Princeton Day School for junior high school, where he began to write music with some of his classmates. Some of these songs (for example, "Golgi Apparatus") would find their way into the Phish repertoire, and many other Anastasio compositions refer to these early experiences. For senior high school, Anastasio attended The Taft School along with The Dude of Life, who helped pen such Phish compositions as "Suzy Greenberg", "Fluffhead", "Skippy the Wondermouse", "Run Like an Antelope", "Slave to the Traffic Light", and "Dinner and a Movie". At Taft, Anastasio founded his first two bands, Red Tide and Space Antelope.
