I have quite an array of musical influences, I'll try to keep it short but covering all the styles(atleast if I can remember them all)
Metal -
Classic = old Priest, Maiden, Manowar, Sabbath, etc
Doom= Saint Vitus, Trouble, Cathedral, Pentagram, etc.
Death = few ...Vader, Angelcorpse.
Melodic Swede/Death= Opeth, In Flames, Amon Amarth, Dark Tranquility,etc.
Black= Emperor, Satyricon, Immortal, Old Man's Child (melodic black and, at times,Gothenburg influenced )
Black/thrash=Venom, Celtic frost, Bathory, Destruction(first album).
Doom-Death = My Dying Bride, early Paradise Lost.
Obscure 60's 70's music:
Heavy rock: Dust, Sir Lord Baltimore, Blue cheer, The Stooges, Mc5, Bang, Captain Beyond,
early Pentagram/Bedemon, Cactus, Hawkwind, Uriah Heep, Deep Purple, etc.
Ambient/Instrumental = Bo Hannson, Tangerine Dream, Mike Oldfield, Vengalis, Kraftwerk, Kitaro, Amon duul ,etc.
British Blues= John Mayall and Bluesbreakers, 60's Fleetwood Mac( before they got the girls in the band! Trust me they were hardcore blues - even Priest covered one of their songs from this era-), Ten Years After.
Classical :
Middle Ages= Various church music
Baroque= Bach, Handel.
Classical=Mozart , Beethoven, Haydn
Pre-Romantic=Beethoven
Romantic=Mussorsky, Wagner, Greig.
That is bassically my spectrum...I have to admit for a while I liked old punk but do not really listen to that style anymore....
Punk: early Misfits, Black Flag, The Mummies, The Nihilistics, The Damned.
I feel like I am forgetting something but I think that about sums it up.
