The way this was set up the abundant acts were on constant rotation playing really short sets so I don't think I managed to quite see everyone, but I saw a whole bunch of good stuff. Here's some mini reviews in no particular order:
Sloppy Seconds did a twin rabbit costumed drum and guitar confusion, smashed up a clock and chalked times on the floor, with the audience trapped inbetween them looking a bit bewildered.
Blue Sabbath Black Fiji were described by someone I overheard as 'fun'. Not really my idea of fun but I can't deny that they are chock full of beans, and every time they play they spill those beans everywhere, all over their stuff, all over the place, and it makes a big fucking racket.
Cementimental freaked out with a modded megaphone, flailing around, fighting with his tools.
Timothy C Holehouse played vile plunger triggered noise with a screaming beard and little hat.
Defibrillators had a very exciting looking drumkit, which failed to excite too much.
Team Brick looked a bit annoyed.
A guy I know only as 'Ryan' played the highlight of the night, an intense strobe experiment that stabbed eyes and ears simultaneously, repeatedly, rapidly, with sharp bursts of blinding light and damaging sound. Extreme, almost agonising, utterly brilliant.
