Based in Los Angeles, the Belle Brigade is a pop duo featuring Barbara and Ethan Gruska, the grandchildren of Oscar-winning film composer John Williams. The Belle Brigade took most of their cues from the '70s, though, creating a sound whose vocal harmonies and bright, breezy pop hooks were heavily influenced by Fleetwood Mac. Using Barbara's connections in the L.A. music scene, they pieced together a backup band and entered the recording studio with producer Matthew Wilder, emerging in spring 2011 with their well-received self-titled debut album. The duo's sophomore long-player, the ATO-issued Just Because, followed in early 2014. ~ Andrew Leahey
