Camera Obscura
Annoying Scottish twee pop band, which is fond of that wall of sound thingy. They have quite a few instruments, but you'd never know, because you can't hear most of them!

The recently released My Maudlin Career, which is probably their best effort to date.

They are continually compared with Belle & Sebastian for some reason, which is weird, because while they both produce pretty twee pop music, you can actually hear the complex instrumenation behind B&S's melodies. Personally, I don't see it.
That kid thinks that Camera Obscura is better than Belle & Sebastian, but he's an idiot.
