I've seen Frightened Rabbit a couple times. They put on a good show. I saw them last Fall with The Twilight Sad and We Were Promised Jetpacks... both are great bands.
If you're into Frightened Rabbit, there is a new band also out of Glasgow that is releasing their first album in late April that sounds promising from what's been released... they remind me of Frightened Rabbit quite a bit, but having a Scottish accent helps...
