Wild Belle - "Keep You"
I had no idea who brother-sister duo Wild Belle were before they opened for Tennis a couple of years back and while Tennis were incredible, Wild Belle stole the show. I am likely a bit biased as any band that has a sax player (especially one who plays the baritone) is immediately a winner in my books. Beyond the sax Wild Belle blends rock, folk, jazz, reggae, and probably a few other genres a whole lot of seriously catchy songs, as is clear in their first single from last year "Keep You". I recommend giving their whole album Isles a listen if you get a chance.
