The compelling bluesman Otis Taylor has been described by Billboard as "one of the most innovative and thought-provoking blues artists to emerge in the last 20 years." Definition of a Circle' is a stirring 12-song set from 2007 that covers a wide cross section of emotionally charged themes ranging from the personal to the political. It is noteworthy for its diverse and outstanding cast of guest musicians: the late British blues-rock guitarist Gary Moore is featured on three tracks and blues harpist Charlie Musselwhite and jazz pianist Hiromi appear on one track each. And, as always, Otis' daughter Cassie Taylor adds a layer of haunting vocals to the set. Personnel: Otis Taylor (vocals, guitars, Ome banjo), ary Moore (lead guitar - 1,6,8), Charlie Musselwhite (harmonica) (3), Hiromi (piano - 10), Cassie Taylor (bass, vocals), Josh Kelly (drums), Brian Juan (organ), Jack Hadley (guitars), Ron Miles (cornet), Rich Sharples (mandolin), Nick Amodeo (mandolin), Zach Miskin (cello), Ben Sollee (electric cello) and others
