Rush - Tom Sawyer is a masterpiece and just so trippy.
Jefferson Starship I always enjoyed this one.
I know it's a ballad and all but I really loved the guitars in this Kansas song.
Talking of the godfather of metal this is my favourite ever song Ronnie James Dio did.
Blue Oyster Cult wise I liked Don't Fear The Reaper but I really liked H.I.M.'s slow, heavy, dark version. I know it won't be for eveyones taste though but I am a fan of the band H.I.M.
I'm just chucking this one in as it is just a trippy song.
