The story behind Big Deal is simple but effective. American boy meets British girl to bring bedroom drift-rock guitar songs to life. It’s the sort of chemistry that sets the “are they/aren’t they?” lovers-in-rock debate in motion.

With the strength of material they have, though, they won’t need any such rumours and look set to achieve great things. This is down to the ease with which their songs are assimilated into your subconscious.

Vocally, Kacey Underwood occupied the lower register while Alice Costelloe naturally floated around the top end. It proved to be a combination that meshed well together without much needed in the way of production, which is probably part of the duo’s obvious appeal.

There were opposing timbres with their guitars too, but, as with their vocals, these clustered to create one sound. Underwood played a nylon-strung acoustic guitar, plugged in and reverbed out with just a pinch of crunch to it.

Costelloe’s electric playing didn’t over-awe, although her rare lead lines hinted at what could be if she stepped to the front musically.

As things were, they both seemed hesitant to take the limelight, instead sharing it between them. A full band would fortify some already-decent songs, but could put a strain on their relationship.
