Apparently, with hushed, early-hours dynamics and an undertow of sexual desire, the xx's debut album is a compelling listen. The band's influences are drawn from outside the indie canon – the xx are famously fans of modern R&B, which might account for the album's preoccupation with sultry yearning, not a mood indie music traditionally conjures: it sounds original, but isn't abstruse enough to scare less adventurous listeners. Already on an upward trajectory, you can imagine the profile boost of the Mercury finally pushing the xx firmly into the mainstream.
