The recent good weather in the UK has meant we've been looking for new music to provide the soundtrack to days spent on the beach, in the park, and holiday nights. If you fancy something a little different, then look no further than new Topshop favourites alt-J (∆). This band may both a mathmatical symbol and its Mac keyboard shortcut, but that's just where the weirdness starts! The triangle symbol actually represents change, which is fitting for a band who make noises like you've never heard before.

Comprised of four friends who met at Leeds University, alt-J (∆) create a strange mixture of folk vocals, hip hop beats, harmonies and huge synth sounds. Even the band members Gwil Sainsbury (guitar/bass), Joe Newman (guitar/vocals), Gus Unger-Hamilton (keyboards) and Thom Green (drums) admit that they don't really know what genre of music they fit into.

alt-J. They really love triangles!

Whatever it is, we are currently loving their debut album An Awesome Wave, which was released this week. Their strange songs just seem to fit with summertime – here at Topshop HQ we're playing alt-J (∆) on repeat and hoping we catch them at festivals this year. You can listen to the album for yourself below.
