Blows Against the Empire is a concept album by Paul Kantner, released in 1970 under the name Paul Kantner and Jefferson Starship. It is the first album to use the "Starship" moniker, a name which Kantner and Grace Slick would later use for the band Jefferson Starship that emerged after Jack Casady and Jorma Kaukonen left Jefferson Airplane. From a commercial standpoint, it performed comparably to Jefferson Airplane albums of the era, peaking at No. 20 on the Billboard 200 and receiving a RIAA gold certification. It was the second album to be nominated for a Hugo Award in the category of Best Dramatic Presentation.
