A walking encyclopedia of musical instruments and styles, Bull illustrates the sheer breadth of his mastery on Jukebox School of Music. Overdubbing guitar, bass, piano, synths, drums and percussion -- or combinations thereof -- he ventures into bluegrass, samba, R&B balladry, country, and Bach's "Brandenburg #5." For "Truth," jazz drummer Billy Higgins joins Bull and his oud to examine Asian music, while "Continuum for Guitar" explores Middle Eastern modes. Exhaustive and exhausting. ~ Jason Ankeny, All Music Guide
