Sorry to be off topic, but I just had to pick up that statement.
There are tons of classic examples of bands where the drummer is technically bad (if they came up with just the right sound is something debatable).
The first example are the Beatles. C'mon noone can convince me that Ringo Starr is a great drummer.
Rolling Stones drummer Charlie Watts is technically very bad - it has been talked (same as Ringo) over and over again - because it's obvious. O.K. O.K. he provides the steady bead, he has soul etc. etc. but he is still a bad drummer.
I will not go into certain other famous bands (which I also like)where I think the drummer is bad.
Bad drumming for me is NOT about simplicity. It's a drummer who tries hard to keep it steady, but he is unable to keep it real stead, just enough not to ruin the band.
A more extreme example is "The Who". Keith Moon didn't even know hoe to vome up with a straight basic rock groove. He basically hit the kick drum, toms and cymbals as if he was playing one huge drum fill all the time. It was bassist John Entwhistle who came up with a technique to provide the notes and the steady groove. To back up my statement: this exact situation is used in the Berklee "Style Writing" course. So it can't be that open to interpretation. Fact is: the end result works.
So there ARE great bands with weak drummers (or those who have a weak technique) - and if the drummer doesn't mess up completely and serves the purpose - it's fine with me.
Phil Collins said in a 1990 interview for a BBC Scotland documentary aut Genesis: Take a bad band with a good drummer and it still sounds good. I'm not that sure. I guess he was selling himself - and the reputation of drummers - a bit. Why not?
My opionion: it all depends on how the band works. The Police were (are?) great to a very large part because of Copeland's great and inventive drumming. He is irreplaceable because he is part of the band's sound.
On the other hand I never liked Supertramp drummer Bob Siebenberg, who always sounded nothing more than a good session drummer with his chops together, but he never really put any soul into it (or so it sounds to my ears).
I am talking about rather "straight" rock drummers of course. If you start with jazz/fusion you get to some guys who are so incredibly good, they won't fit into any band even if they tried - that's why they do clinics, workshops, demos and lessons on DVD...
