"Flan is like a woman" (track 21 on Paradise) is a composition that is fun to describe from a
polyrhythmic standpoint. In the middle section Leo plays a rhythm in seven on the bass drum.
with a four (quartuplet) on the hi-hat on top of the seven (with a snare on the second and a floor tom on the fourth beat of the four).
Julie plays a melodic line which is 5 over 3 of Leo's hi-hat beats
So in other words, it's a five over three of the four over seven.
