I happened across an old recording of this drum pattern I'd written for basement audio lab. It was a crappy demo version consisting of me tapping on my legs and kicking the mic stand. It was virtually unlistenable, with a horrendous click track going in the background. I was surprised to find the pattern came much more naturally to me this time around, and the click was not necessary. I just wanted to make a better recording of the part for future reference. I don't know what prog rock band I'm going to join someday that will have a need for a part in 7/8 time, but you never know. When the time comes, I guess I'll have this to contribute.
Doing fills in 7 is hard. It's not a natural thing to feel when you were raised on groups of 2 and 4. Most people understand 3, I guess. Waltzes and such. Sometimes you'll hear radio stuff in 6 (which is really just 2 groups of 3, or 3 groups of 2, depending). 5 and 7 are a lot trickier, since you're mashing a 2 and a 3, or a 4 and a 3, or 2 twos and a 3 together at once. Makes it harder to find the downbeat. Actually, what I really like to do is carry it over 2 measures, then the "down" beat becomes the "up" beat for the second measure, before it turns back around again.
