Well. i wish that Martin in person would answer this question... but if any of you guys can help me it would be very cool too.
I'm a drummer and i'm really into this extreme drum, you know, and i would like to know if any of you know how to measure the speed... for example, how fast is April's Ethereal in BPM?(the double bass drums), how many kicks Martin can do in a minute?, etc, etc.. anything related to Tempo Theory would be very appreciated here!...
well i'm all eyes now...
