Pentagram are a long-running American heavy metal band from Virginia, most famous as performers of Sabbathesque metal. The band was quite 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 Place of Skulls, Internal Void, Spirit Caravan, among many others.
