I play with a drummer who has this problem more than many. Perhaps it's a confidence thing, perhaps it's because he's an intense worry-wart, and I think he also watches too many drumming technique videos instead of just paying attention to the flow and groove of music. Anyway, you can just hear him [i]thinking[/i] in the way he plays. I keep telling him to chill and let it flow, but it's like he's forcing the drum parts into being, beat by beat, and then trying to chuck in some 'triplets over a half-time quarter note feel' in a fill when a simple 'bip-bap-crash' would do. Always bloody thinking, and it drives me nuts sometimes. He could be so much the better player if he'd just shut the hell up in his own head, and [i]let[/i] it happen, instead to trying to [i]make[/i] it happen.
This ^^ is so true!
