Some of them that I liked:
#07 impressed at how much it feels like human rhythmic improvisation
#11 nice ambient gamelan feel
#12 upright bass party in a medieval dungeon
#16 very Autechre-ish
#17 hilariously spastic rawkin'-out, actually has some sense of harmonic motion between two chords
#18 slightly impressed that you can fit passable footsteps and a thunderstorm in 140 characters
#20 glitchy robo-cicadas are fighting for territorial rights to my brain! nice stereo separation.
#22 has a bit of narrative to it, turn your headphones down, though, it gets loud
