At Lollapalooza Brazil a couple of weeks back, Band of Horses delivered a surprise acoustic set, which included the debut of a brand new song. According to an issued press release, the band is currently working on their fourth LP with legendary producer Glyn Johns, and the untitled cut is the first piece of new music to “go public” since the collaboration began. Watch the live footage below.

The as-yet-untitled album will be released later this year. In the meantime, you can catch the band when they play Florida’s DeLuna Festival in September.
