But Keith sounded the way he did because he _didn't_ know what he was doing. He was just bashing away. Going by feel. And it was great.
Perhaps you're right about that, I'm not sure, but maybe. I did hear Townsend in interviews complain about Keith not laying it in like a typical drummer, so maybe he didn't know what he was doing. But playing by feel isn't indicative of not knowing, nor is not doing what's typical - regardless of how well it just happened to turn out - if he didn't know what he was doing. -- Watching him during live concert footage, I'm always impressed at how attentive he "appears" to be, deeply focused on Pete's playing the most, but also being quite sensitive in his dynamic range, to glorious extremes when it's time to get quiet, as well as bombastic. If he truly didn't know, he sure had an intrinsic and orchestral way of playing. I think that came from building what he did conceptually on Pete's writing and playing, which, as Tommy and Quadrophenia illustrate, was quite orchestral - and even in the more guitar/bass/drum songs like I Can See For Miles or Baba O'Riley - both very small ensemble, but orchestrally executed pieces. Keith vibed that from Pete. And both Pete and The Mighty Ox were very dramatic players. Moon almost had no choice

he'd have been eclipsed to play otherwise.
I've had some friends, guitarists, who jam very well one-on-one with drummers, and this is the same kind of focused interaction I've seen as with Moon. Is it wrong for a drummer, when a bassist is present, to focus and create parts based on the guitar? For some drummers, maybe not such a good idea, but playing in the pocket with the bass is hardly the unbreakable law. As one who grew up with a lot of progressive rock, I like both perspectives, but I'm quite thankful when a drummer can swing both ways, whether he "knows what he's doing" or not
In short, playing with any musician should be a give and take interaction, always expecting a drummer to mold to the bass can be a shade short sighted, methinks. Great music - like The Who included - happens when everybody molds to one another freely, by choice, as well as when requested. That can yield both standard formula, when needed, as well as fresh invention. And goodness, we need that.
