Ironically, perhaps, if you go back and listen to Texas Flood and his earliest recordings, SRV played very little overdriven songs, esp. on Texas Flood. People only perceive or remember, for whatever reason, that he played the Tubescreamer cranked up, which simply isn't true, for the most part. Players like Johnny Lang and KWS really, REALLY ruined the blues: always overdriven, always like their heroes. They are not the only ones, but the only ones to come to mind. The Black Keys and The Racounteers (sp?) are playing some inventive blues-based materials.
