The brainchild of Anthrax guitarist Scott Ian, Motor Sister is an all-star hard rock collective built for the sole purpose of celebrating and playing the songs of Los Angeles-based groove/blues-rockers Mother Superior, who broke up in the early 2000s after releasing eight studio albums and moonlighting as Henry Rollins backing band. Debuting in 2015 with the all Mother Superior set Ride, the band delivered a collection of original songs on their 2022 sophomore effort, Get Off.
