It's happened to me more than once, that I write cool riffs and tab'em up in Guitar Pro, so I set a tempo I think is appropriate, program the drums, bass, etc. and then I show it to a friend/co-writer and he's like "who the fuck's gonna play that on drums??" so it got me thinking, what would be a sensible limit for blastbeats to be played by a good drummer (like not something only 5 guys in the world could play)? I did 150 bpm and my buddy said I'm crazy, and thinking about it, it does sound a bit hard on the drummer, but it sounds so good that way it sucks to make it slower, I slowed the fast parts down to 135 and it's Ok, but faster made the riffs sound better. Has this ever happened to you?
