Initium is the 1984 debut album by American deathrock band Samhain, released on lead singer Glenn Danzig's independent record label Plan 9. In various interviews, Danzig stated that the album's title, which translates from Latin to English as "beginning", represents his new start after disbanding his prior band, Misfits, in 1983. Most of the final track, "Archangel", was actually recorded in March 1981 with Jerry Only, and was originally meant to either be a Misfits song featuring Dave Vanian or a track for the band the Damned. The track "Horror Biz" likewise dates to Danzig's Misfits era, as it is a new version of "Horror Business" with different musical arrangements. The album was recorded at Reel Platinum studio in Lodi, New Jersey, excluding the introduction which was recorded at Eerie Von's home on a four track cassette.

Samhain was an American rock band formed by singer Glenn Danzig in 1983, immediately following his departure from The Misfits. Glenn Danzig originally planned Samhain as a side project with Eerie Von. After the Misfits' contentious 1983 dissolution, Samhain became Danzig's full-time band.
