To be fair, the file is very heavily compressed (64 kbps) so that would account for some of the aural displeasure Abark mentions.
You should cut out as much crowd as you can in the beginning, mainly because, after spending 1 minute listening to them, they stand out even more once you guys kick in.
I think this is a very poor live recording, you really can't hear things well enough to make any real critique, the singer sounds like he might be good in person, but his voice is not only squelched by the ambient noise, it's also destroyed by the compression.
I get a kind of "there's a band playing in the corner, but no one cares, not even the band" type of vibe from this recording
But I really can't say anything about the song or the playing, the recording quality is so shoddy that it wouldn't be fair.
