Pentagram is an American heavy metal band from Alexandria, Virginia, most famous as one of the pioneers of heavy metal, and the subgenre
of doom metal in particular. The band was prolific in the underground scene of the 1970s, producing many demos and rehearsal tapes, but did
not release a full-length album until reforming in the early 1980s with an almost completely new lineup. Throughout the band's history the only
constant member has been vocalist Bobby Liebling. The revolving lineup of Pentagram has featured many well respected musicians in the local
doom metal scene, with members spending time in other acts such as Raven, the Obsessed, Place of Skulls, Internal Void, Spirit Caravan,
among many others.
