Drummer in my band frustrates the B'Jesus out of me. He's a great band member and is always reliable, organizes stuff, sets up the PA etc. etc, but when it comes to keeping time he drives me nuts. Unlike most 'dodgy' drummers, his favorite way of aggravating me is slowing stuff down. We've talked about it over and over and still it goes on. I've tried to deal with it in real time but I end up pushing the beat at the places where he habitually slows down but to no avail. It ends up sounding a complete mess and like I can't keep time either, so I invariably end up slowing down as well. I've suggested practicing to a metronome but he'd rather spend his time working on fancy fills and stuff which rarely come off in real time. Some songs he'll actually count in at the right tempo but then immediately start off about 20% slower. Sorry for the rant but it was an opportunity to vent something I've had years of.
