I saw a band called Wintersleep at Great Escape that I'd never heard of, but seemed to pull a decent crowd.
Went to see them again last night at Barfly and the place was pretty busy again, even though they're not from these shores.

Am I just deaf, dumb and blind not to have heard of them?

Have you been taken aback by how popular some bands are? And I'm not talking about those who just bring a coachload of their mates from school to every gig.....
