I'm a pretty good guitarist, and I can play some tricky rhythms (weird time signatures, syncopation, some of the easier djent stuff) but I've always had trouble when my drummer starts to play anything that sounds punk. I like punk music a lot so this confused me at first, but I realized that it's because whenever I hear bass-snare-bass-snare played that fast, I feel the snare is the down beat since it stands out so much and that screws me up.
I programmed some drums into my sequencer and tried practicing over that and slowly speeding it up until it gets to the point where I get the downbeat mixed up. I'm gonna keep working on that, but does anybody have any other advice on this? This is a fundamental issue in my playing and I'd like to fix it.
