Curse of the Hidden Mirror is the fourteenth studio album by the American hard rock band Blue Öyster Cult, released in 2001. The only single from the record was the poorly received "Pocket". Lackluster sales led to the band being dropped by their label, Sanctuary Records. BÖC has not recorded a studio album since.
The title of the album is taken from a song contained in the unreleased album by the Stalk-Forrest Group, the band that would later become Blue Öyster Cult, recorded in 1970.
John Shirley, a renowned author of cyberpunk science fiction, wrote the lyrics for many songs of the album.
The song "Out of the Darkness" was originally featured in the 1992 film Bad Channels, which Blue Öyster Cult recorded the soundtrack for, although the song was not included in the soundtrack album for the movie.
