Their event listings used to be my go-to place to find out about concerts. The problem is they have a bug they've never fixed (after at least 2 years) where you can't see events happening on the current night. I think it's related to timezone, and the fact they are based in the UK.

Now I've got songkick, which kicks ass at keeping me informed about shows. But the whole reason songkick is so effective for me is that I imported my listening history from last.fm when I first signed up.
