Firecrackers: The Best of Mass Production is a comprehensive collection of the late-’70s soul band, featuring the majority of their R&B hits, including “Welcome to Our World (Of Merry Music),” “Turn Up the Music,” and the Top Ten R&B hit “Firecracker.” The compilation spans from their first album in 1977 to their farewell 1983 record, hitting every peak along the way. Though the material isn’t always consistent — some of the lesser-known songs have dated rather badly — Firecrackers remains the definitive retrospective of Mass Production. – Stephen Thomas Erlewine
