If you're unaware, there's a pretty cool British band called Bring Me The Horizon, who have an even cooler song called "Drown."
Recently, the Aussie boys of 5 Seconds of Summer graced BBC Radio's Live Lounge to give the world their passionate rendition of "Drown," and it was incredible.
Calum and Luke were totally killing it on the verses. The boys were joined by a small string ensemble that gave their version a much more tender feel than the original.
Oh, and they totally SLAYED the harmonies while Ashton rocked the percussion.
