Opeth - The Moor
Electric Wizard - Electric Wizard ... for me, the slow swinging chugging is just my style through and through
Iron Maiden - Number of the Beast ... just clicked with me, the fluid solos, the ending, brilliant
Akercocke - Horns of Baphomet ... harsh sounding chords and rung out notes have had an effect on me, love it
Isis - Divine Mother (The Tower Crumbles) ... dissonant sounding chords, heavy riffing, great :)
Anathema - We, The Gods ... the chorus laden clean part at 5:47 is something that i've incorporated into my playing style
My Dying Bride - A kiss to remember ... the lead parts combined with the viola
Esoteric - i can't really pinpoint a single track (or even an album), they've shaped my sound a lot, really effect-laden, soundscapey sounds, something which i love to just turn the amp up, whack on the chorus' and delays, and just chill out :)
Black Sabbath - War Pigs ... yea, you know it!
Moss - again i can't pinpoint a track, but after i saw them live years back, the hyper-slow style just struck a big chord with me.
Certainly for me, the slower side of things really appeals, and that's where i've found myself playing mainly. Slow, heavy, simple riffs, interspersed with the odd fast section, and nice big chorus and effect cover clean passages, is what makes me tick on the average day.
