A night at the Pony

Went to a breakcore evening at Pony last night.
Some live acts, some DJs. The best live guy was definitely Sado, who played early in the night. DC105 was starting to sound good too, but it was getting late and I left halfway through his set.. I doubt many other people heard him, as two avant garde noise acts prior had just about emptied the club.
The first avant garde guys had one screaming incoherently into a microphone while another guy played with filter effects over white noise. Rather unlistenable.
The second pair were initially more interesting, just due to the setup - one guy had an AM/FM radio and a cassette player, a bunch of cassettes, and a few guitar effects pedals. The second guy then knelt on the floor in front and bashed away at more effects pedals, and occasionally ground up and popped some bubble-wrap with an odd expression on his face. Again, the end result was like walking down a very windy tunnel.

I know it's performance art, but damnit, couldn't they at least put a slight hint of rhythm in there?
And maybe have a warning prior that says "Please don't leave, there will be normal* stuff on afterwards again".
(* Well, as normal as breakcore and rhythmic noise can be..)
