But no, I was messing about with a weird progression that I don't totally understand, it starts on D and then goes down to C and A# but uses the same notes within the D chord, even though the D chord is using notes more commonly associated with a G, I'm sure there's a name for it but I dunno, probably some inversion. Anyway, then I started tremolo picking with some weird effect on and I messed about with a wah and a pitch shifter, it sounded kinda cool.
