Limited marbled vinyl reissue celebrating the 40th anniversary of Relentless, the legendary album by Pentagram, pioneers of American doom metal. Formed in the early 70s, Pentagram, under the leadership of the charismatic Bobby Liebling, left its mark on the history of underground heavy metal with its notable influence from Black Sabbath and The Groundhogs. Relentless, originally self-released in 1985, was renamed and reissued in 1993 by Peaceville. This essential album, with its timeless metal anthems, Bobby Liebling’s unique voice, and the virtuosity of guitarist Victor Griffin, remains a pillar of doom metal. This record has also inspired many generations of bands. For this anniversary reissue, Relentless is presented on limited marbled vinyl.
