If there's any band singularly more responsible for the 'Doom' genre becoming distinct from simply 'Heavy Metal', it's Pentagram. Their history is an incredibly long and confusing one (just looking at the wiki entry can make one's head spin), so I'll post a long and meandering history for those interested and then boil it down for those not.

This lineup of,,, and would remain intact for the next six years, and though they occasionally performed under different names, including Virgin Death, Stone Bunny, and Macabre (the last of which graced their first single, 'Be Forewarned,' in 1972), they always inevitably returned to. Another element of stability was their musical direction, which never strayed too far from the distorted psychedelic hard rock of heavy metal pioneers like.
