My DJ set at The Penelope Tree went well; it was an early set, and a small night, but quite a few people (not least among them the organisers) were pleasantly surprised with what I had played. All things being equal, it could help me get more DJing gigs in London.
The tracks near the start went down particularly well, though some people thought I had played two Stereolab tracks side by side. And the C86 janglefest towards the end also found quite a few fans.
The venue's system was a bit on the naff side; 2 old consumer-grade CD players, one of which wouldn't play burned discs (none of that fancy CUE button stuff here), and rather badly set up speakers. I played mostly from one CD player and my two MP3 players (I dusted off the old Archos for this; I actually prefer it for DJing to the iRiver, mostly because its firmware (or, to be precise, Rockbox) doesn't second-guess you and pull you out of the directory you're looking at if you do something else for a minute.)
