well it comes intrinsically to me, wierd time signatures.
Thought 2: Silent Amender has a 3 bars of 3/4, one bar of 2/4 before going 4/4. I didn't pull that off by thinking, it first came from playing and improvising and then I realize what I did.
Bye Pluto, also from At Ease, has a 7/8 time signature which variates with a 4/4.
The bassline of Beach Arab tweaks Up the Beach's 4/4 and uses something like a 9/8 time signature I think, I don't remember.
