As of late I've noticed that I tend to really struggle when playing with drummers who play non-traditionally or busy in ways that I don't expect. The problem is definitely with me and not the drummers... it just feels like my brain short fuses when they start comping outside the box, messing with the beat, or flipping the hats around. I don't feel like I have any issues playing with a click or a straight ahead drummer, I really just run into trouble with the busier guys. Most of the drummers I've worked with over the last few years have been more straight ahead traditional guys and I think I've gotten used to that style of playing. So my plan of attack is to reinforce playing with the metronome while practicing and start working through some albums with more esoteric drumming. I also plan on checking out the iPad app mentioned in a thread below... I think that would be helpful. Any other advice?
