well this a bit tricky.
rock singer for me is definitly layne staley. not only did he have an incredable voice but he also wrote incredable music along with jerry cantrell and had the vocals to back it up. layne was simply terrific
* also like james hetfield, lemmy, and zakk wylde
rock gutairist in my opinion is none other then zakk wylde! he plays so fast but not only that sang for his band black label society and has a terrific voice he was one of my picks for best vocalist. but when he plays gutair its something special
rock bassist i dont know why but i really like robert trujillo from metallica. ive been watching alot of metallica videos, and documentaries so thats probably a part of why but yeah i think hes really fast and talented.
rock drummer- again i like lars ulrich of metallica but not as much as mikkey dee from motorhead. wholey crap can that guy play the drums!
keyboardist.... have no f****** idea.
