Back It Up!! is a promotional "live" album from Nils Lofgren initially released 1975. The title of the original vinyl LP was Back It Up!! – Nils Lofgren Live – An Authorized Bootleg. Although the recording was officially released by A&M Records, the artwork was designed to give the appearance of a live bootleg recording, similar to Decca Records' original vinyl release of the Who's Live at Leeds in 1970, which was a legitimate live album designed to look like a bootleg.
