I'm a drummer, but I totally echo the OP's thought train. I've spent quite a few hours listening and picking apart stuff from the Masters (giants such as Joe Morello, Terry Bozio, Neal Peart and many more...), wondering in awe at their dexterity and imagination. I've spent decades, also, playing in variety orchestras, small bands and rock groups, and have never been called upon to play anything even approaching what those folks do. Of course, I have never gravitated in the musical circles where my colleagues and fellow musicians play at that level, either, and in my current band (The Daub'z...), I don't need any more than basic rudiments for playing Radiohead, or Noir Désir. Did I waste my time studying all of that flashy stuff..? I don't think so (and, in any case, what little I did try to emulate was a very poor ersatz, not worthy of insisting upon...). I'm very content to be simply the 'motor' of the beat, playing relatively simple stuff (modestly...) pretty well. For anyone starting out, I'd insist on working on the Rudiments, the basis of all techniques, really, and encourage the curiosity to look at what the experts are doing, but for every Top Gun, there are thousands of competent players doing sterling work every day, out of the limelight. Maybe I lack ambition, but I don't have the dedication (nor the raw talent..!) to be 'right up there'; I'm quite complacent and content to do what little I can as best as I can for as long as I can, and no more.
