I remember first reading that influences/thanks list and noting a few other essential exclusions.
Here's the list, courtesy of RYM's Chaosmonger:
"Gaz thanks: Necromandus, Gracious, Tudor Lodge, Forest, Captain Beyond, May Blitz, Warhorse, Monument, Clear Blue Sky, Black Widow, Curved Air, Comus, Saturnalia, Principal Edwards Magic Theatre, Yes, ELP, Affinity, Caravan, Camel, Atomic Rooster, Mellow Candle, Gong, King Crimson, Aphrodite's Child 'and all other obscure 70s progressive/folk bands and all NWOBHM bands' (ha, really covered his bases there)
The band thanks: Black Sabbath (I can vouch for this band), Saint Vitus, The Obsessed, Pentagram, Solitude Aeturnus, Witchfinder General, Asylum, Goblin, Revelation, Warcry, Cirith Ungol, Melvins, Merciful(sic) Fate, Confessor, Nigro Mantia, Black Widow, Diamanda Galas, Dream Death/Penance, Angel Witch, Godoreah, Mike Small's Rollercoaster, Death SS, Paul Chain, Dead Can Dance, Count Raven, Internal Void, Blue Cheer, Bomb Culture, Loch Ness "
Missing Trouble and Candlemass, but whatevs, still looks pretty damn thorough to me when it comes to things of doomy and psychedelic nature. If a band like Pagan Altar had the reach some allege, you'd think they'd be a fashionable thing to namedrop. Fucking Nigro Mantia even, but no Pagan Altar?
