I can participate in this theme!

Rock Werchter 2008. I worked as a volunteer and saw a crap load of bands. (notably for me:) Sigur Ros, Radiohead, Jay-Z, My Morning Jacket, Slayer, Hot Chip, Ben Harper, MGMT, Band of Horses, Hercules and Love Affair, Beck, Grinderman, Justice, and Devotchka. I slept a total of 4 hours for that. I've also met about 20 people after the fact who were at that festival. One of whom used the same way of locating people as we did and we completely threw eachother off so we gather that we actually did meet at this thing but didn't actually know!
To the left: poster I got at a Kokomo gig; to the top: Bear in Heaven in what is possibly Scotland's tiniest venue more above; more to the top: various club nights that are pretty rad (or make pretty rad flyers).
