Anthony Frederick "Tony" Levin (born June 6, 1946) is an American musician and composer, specializing in electric bass, Chapman Stick and upright bass. He also sings and plays synthesizer.Levin is best known for his work with progressive rock pioneers King Crimson and Peter Gabriel. He was also a member of instrumental-prog rock/jazz fusion group Liquid Tension Experiment; the King Crimson-related bands Bruford Levin Upper Extremities, ProjeKct One and ProjeKct Four; and currently leads his own band, Stick Men. A prolific session musician since the 1970s, Levin has played on 500 albums, including those of Cher, Alice Cooper, John Lennon, Sarah McLachlan, Stevie Nicks, Pink Floyd, Dire Straits, Lou Reed, Tom Waits, Buddy Rich, The Roches, Todd Rundgren, Seal, Anderson Bruford Wakeman Howe, Warren Zevon, Kevin Parent, Laurie Anderson, Kate and Anna McGarrigle, Gibonni, and Jean-Pierre Ferland. Additionally, he has toured with artists including Paul Simon (with whom Levin appeared in Simon's 1980 film One Trick Pony), Gary Burton, James Taylor, Herbie Mann, Judy Collins, Carly Simon, Peter Frampton, Tim Finn, Richie Sambora, and Claudio Baglioni.
Levin helped to popularize the Chapman Stick and the NS upright bass. He also created "funk fingers", modified drumsticks attached to fingers used to hit the bass strings (which sounds similar to slap style bass). Levin is also one of the first bloggers, as he began sharing his tour experiences in a diary fashion as early as in 1996, one year before the terms "weblog" and "blog" were coined. In 2011, Levin ranked second (behind John Paul Jones) in The "20 Most Underrated Bass Guitarists" in Paste magazine.
