Todd Strange: Todd Strange (born January 31, 1966) is a bassist who played live on the first Down album "NOLA" and with Crowbar.  Forming Crowbar with Kirk Windstein (Down), Matt Thomas and Craig Nunenmacher (Black Label Society), they released the best-selling albums of the band's discography.  This included the Crowbar self-titled LP with the hits "All I Had (I Gave)", "Existence is Punishment", "No Quarter" (by Led Zeppelin) and "I Have Failed", produced by Phil Anselmo.  By 1994, Phil put his band Pantera to the side and resurrected Down which was sidelined for Pantera in the late 1990s.
