Curse of the Hidden Mirror is the fourteenth studio album by American hard rock band Blue Öyster Cult, released in 2001. The only single from the record was the poorly received "Pocket". Lackluster sales and poor relations led to the band being dropped by its label, Sanctuary Records. BÖC has not recorded a studio album or held a record deal 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.
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. "Showtime" was originally written and recorded for Cultösaurus Erectus but did not make the final cut.
