Commonly unfairly viewed as also-rans to their German counterparts Scorpions, Accept was definitely more metal and innovative in their songwriting, sometimes to the point of being anti-commercial (e.g. Son Of A Bitch- terrific song). Another band that I think should have been bigger in their heyday- they had a great frontman in Udo, the riffs and musicianship to back it up, and a great stage gimmick.
