Crom tech (One of the greatest bands ever, so original)
Orthrelm (Guitarist from crom tech's new project)
Kaito (One of their guitarist just makes these weird noises as effects, but they fit really well)
Don Caballero
Reversal of man (Not that weird, more interesting)

Coughs!

Furze
Striborg
??

Comets On Fire. yes indeed

Oneida have some weird stuff, Each one Teach one especially

Yeah

Since Polvo is mentioned so often, i would suggest Erectus Monotone. A little known band from the same era, same area. Their "Close Up" ep is out of print, but u can find it here and there. Its like Polvo but less disonant and more real songs. Fantastic hidden gem.
