for example in the hello goodbye music video at 1.16 https://youtu.be/rblYSKz_VnI?t=1m16s  ringo starr does the same thing, suprised with a slightly opened mouth while doing a drum fill. were you inspired, or was this coincidental?
i think it relates more to the fact that the fill occurs and there is sort of an empty space right after (no kick). so it's almost like there's a big fill into nothing. feels kind of like ripping the rug out. i think that's what i was expressing ... sort of a jumping feeling
