I can't get Surfer Blood's Swim out of my head. I love the shouty, echoing vocals which are great for singing along. I love the big and crunchy guitar hooks. This song is like a cotton-candy flavored shot of adrenaline. I hope the rest of the album is like this.
From the little I've read, Surfer Blood are from Florida and they have one album called Astro Coast. Otherwise, I don't know much about these guys (I can't find a main site), but you can stream more tunes here.
