It's the Mystery Jets.

Really nice jam by Count and Sinden featuring Mystery Jets. E sent this over and I am really enjoying this. Great single. Also just so happens that my favorite dudes on the planet decided to do a remix of the Mystery Jets as well. You should check out that below thanks to Eskimo Records.
