UK eight-piece Caroline's eponymous debut album often cascades with force like an avalanche, squalling and rumbling on the edge of all-out collapse. At other points they slip back into impossibly fragile moments of quiet – a simple bassline or a rattle of snare the only sound amid a dark sea of silence. Caroline know exactly the right balance between restraint and release. These songs are expansive and emotive pieces, their rich palette drawing on a mixture of choral singing, Midwestern emo and O'Malley and Llewellyn's roots in Appalachian folk.

"Sometimes things sound much better when there's empty space," says Llewellyn. "Sometimes you might populate [a song] with too many things and forget that an element on its own is enough." Elsewhere on the record the band have employed a collage-like technique, combining snippets of lo-fi recordings from a myriad of different locations – a barn in France, the members' bedrooms and living rooms, the atmospheric swimming pool in which they also filmed sublime live sessions for "Dark Blue" and "Skydiving Onto the Library Roof" – with more traditional group sessions at the Total Refreshment Centre and their studio in Peckham.

The growth that began as a scrappy guitar band above a pub many years ago is still continuing. Caroline's astounding debut album is merely the first step.
