From the High Fidelity movie…

Rob Gordon: I will now sell five copies of “The Three EPs” by The Beta Band.
Dick: Go for it.
[Rob plays the record]
Customer: Who is this?
Rob Gordon: The Beta Band.
Customer: It’s good.
Rob Gordon: I know.

This is what they were reffering to – The Beta Band – Dry the Rain:

First Aid Kit is a band by a couple of girls, singing mostly sweedish folk music songs. It sounds quite interesting, specially as some songs – like the one in this post -, feature an intruiging mix like sad lyrics and joyfull instrumentals.

They will release their next album, The Lion’s Roar, from which two singles have already been released - The Lion’s Roar and Emmylou.

Below you can listen to Emmylou.
