The Warner/Reprise Loss Leaders were a series of promotional sampler compilation albums released by Warner Bros. Records throughout the 1970s. Each album (usually a 2-record set) contained a wide variety of tracks by artists under contract to Warner Bros. and its subsidiary labels (primarily Reprise Records); often these were singles, B-sides, non-hit album tracks, or otherwise obscure material, all designed to arouse interest in the artists' regular albums. Also found on some were humorous, bizarre interstitial audio material—clips from old records and movies, short skits, found sound, etc.--and most albums featured clever, humorous cover art and liner notes. Most of the 1970s albums were compiled and annotated by Barry Hansen, better known as Dr. Demento.
