alaysa, i love many of the bands you listed, but they have nothing to do with julian's request! julian, i'm going to actually follow your request!:
thinking fellers union local 282 <--- like polvo.. but better!
truman's water <--- like polvo but less melodic/more insane
scissor girls <-- deconstructed no wave with poppy parts occassionally!
bride of no no <--- super arty/abstract with chick singing; prog no wave; 10 minute no wave songs with like 500 parts; amazing
sun city girls <-- you know them, right?
the vss <-- art punk something; "nervous circuits" reminds me of if you mixed the first 3 wire albums in a blender
omoide hatoba <--- haha; alternates between pure art to pop to every genre in between; just amazing
cerberus shoal <-- get "mr. boy dog"; completely abstract/rocking/arty/awesome
