Skidrow fricken ruled back in the day. I loved there music and the concerts were great.
The best vocalists in my opinion are and not in any given order: Scott Weiland, James Hetfield, Chris Cornell (yes I will give you that one pD even though I am not a big Audioslave fan), Billy Corgan, Eddie Vedar, and Bruce Dickenson.
Right now I got Bullet with Butterfly Wings by Smashing Pumpkins.
