Opeth - Under the Weeping Moon

This is one of my favorite Opeth songs to play on guitar. This is from Orchid, way back when Opeth wrote long rock epics with simple, though fast, riffs. The complexity was still present in the music, not from individual guitars but from a combined entwining of every riff from each guitar. Mikael's vocals were also harsher and more grated at this time, allowing him to supplement the more melodic riffs at every turn.
