Sorry, never was an EL&P freak.
However, I will tell you who I think is one of the most under-rated (not necessarily the best)of all rock drummers: Mick Fleetwood. Charlie Watts is a close second in that department.
I don't follow many of the newer generation of hard rock bands much, but I must admit I'm very impressed with the quality of some of those percussionists when I do catch a performance on SNL, Leno, Letterman or Conan. Still, like most of rock, there isn't much out there that really gets to me nowadays. There are excellent musicians, sure, but they don't seem to be doing anything that wouldn't have already been state of the art 30-40 years ago. Rock is dead, development seems to be frozen in time, and nothing seems to be replacing it.
