There's something deceptively simple about Armlock. They operate in a subtle register somewhere between slowcore and post-rock, carving pristine hooks out of clean slabs of guitar and drums. Every part is small and straightforward in isolation, yet it's in exactly the right place within the wider arrangement.

'Lifer' is no exception. The first single from their new album Amazing (out in February via Run for Cover), it's a track that creeps along unobtrusively until it stumbles into an Alex G-like chorus of glorious melody; this recedes quickly in turn, and in less than three minutes, Armlock have made their point with the minimum of fuss. More bands need to be this efficient.
