Once again I am reminded that observing a thing changes that thing, and this is particularly the case for bands, which play quite differently depending on their audience. By documenting these bands, I am actually making a difference to them, and it's quite odd to realise that. Watch this and the previous night and you'll see that some of the songs are a bit different. Which is nice for me, as bands that aren't afraid to change songs around and do some improvising obviously stand up better to repeated attendances.
