Unholy Passion is the second release by Samhain, Glenn Danzig's band after the disbanding of the Misfits. The original Unholy Passion EP is now long out of print. In 1987 Danzig re-recorded the guitar and some vocal tracks for the songs, removing the original work done by Pete "Damien" Marshall. The recordings were given new mixes and, with the addition of "Misery Tomb", were released as part of Final Descent in 1990.
