Alt-J were the guest of choice this week on Radio One's Live Lounge with Fearne Cotton. The band popped in to put in a spine tingling performance of their single "Tessellate" and then as many bands before them, they performed a mystery cover. For the cover Alt-J pulled out a haunting rendition of Alex Clare's hit single of the moment, "Too Close". If you missed it earlier in the week don't fret, you can check it out below.
Alt-J's fantastic album An Awesome Wave is out now.
