I am a HUGE Stryper fan, and even if Sweet isn't one of the BEST, he is one of the most SOLID and fun to watch drummers out there.
You are thinking of Rick Allen.. Ricky Rockett just sucks so bad it SEEMS like he only has one arm,
The "Visual Time Keeper", Robert is VERY talented as he also plays guitar, piano, and bass (just not on any album)
I have all of their albums and all of their autographs. Went and saw them when they played at 8 second saloon, very small crowd but still a great show. I had front row tickets and could reach out and trip Michael or Oz if I wanted to.
OK, don't flame me, but...
This is beatbox, not drummers, but the kid beatboxes through 108 Time Signature changes in this Dream Theater song, while showing what each one is with flash cards.. Pretty impressive
