I don't think a mute with a bucket on his head is rock n roll, not does he fit in with the GnR image or style.
He has a playing style that's innovative and unique, and he's talented. I'm even looking forward to hearing his guitar on Chinese Democracy (if it's included). But if you look back on the history of this band, where it came from, etc...BH sticks out like a sore thumb and I think it's better for all parties that he left.
So what new band member is "rock n roll" ? Enlighten me. Maybe it's Finck sitting behind his desk making lil collages.? Or the red headed mute with a wig on his head. Maybe thats why Axl liked Buckethead so much in the begining. Neither talk much and they both wear strange things on their head.
