I'm hearing you. I think this has to happen early on when you're working out a part. Once I'm behind the kit then my ears have to be boss or, as you say, I'm sunk. I've sunk plenty in my time and no doubt will sink again. I find that sometimes the things I do when I'm sinking come in handy on better days.For me the minute I think about doing something I'm sunk. I operate smoother when I'm in a semi hypnotic state, being more tuned in to the larger vibe. It doesn't mean I don't try new stuff, it just means, I have to feel it in order to attempt it. If I try and think of a slick idea, I usually fall off the track.
But that's just me.
Ever try playing an entire song without a fill?
I often play songs without playing a fill, and even more often play just one or two fills, just adding some art deco cornices and a mantelpiece as features while I leave the carpet to the bassist and the others can decide on the furniture, pictures and dust collectors I didn't play any fills in two of the four demo tracks I posted a while ago. There were variations but no actual fills.
Drummer-ish, I like that ... the spirit of taboo. Bring it on!
