The Electric Light Orchestra (ELO) Part II were a British-American rock band formed in 1989 by Electric Light Orchestra drummer and co-founder Bev Bevan. The band also included former ELO bassist and vocalist Kelly Groucutt, and violinist Mik Kaminski for most of its career, along with conductor Louis Clark, who contributed orchestral arrangements to many of ELO's albums and toured as a guest with the original band in its later years; ELO cellist Hugh McDowell likewise briefly performed with Part II in 1991. Alongside these personnel, Part II rotated through several ELO-unaffiliated frontmen during its lifetime, with singer-songwriter and keyboardist Eric Troyer the only one to retain constant membership.
