There is something quite dream-like about a Let's Eat Grandma set.

Firstly, in the hotly-tipped Norwich teen duo's sound – their opening number creates a dreamy, atmospheric sound, with the hum of a synthesiser.

However, much like a dream, there is a charming unpredictability to the Access to Music students.

Throughout the set, in front of an over-flowing Sunrise Arena, the duo showcase their diverse range of talents, flirting with a variety of genres and instruments.

Rosa, adorned in an orange baseball cap and black hooded jumper, changes instruments on a regular basis – leaping from keys to saxophone, to drums, and even recorder, with no warning.

It is difficult to place Let's Eat Grandma's sound – at times they are subtle at atmospheric, at other times frantic and playful.

In each song, childhood friends Rosa and Jenny, both 17, share vocal duties, duelling in a multi-layered approach reminiscent of another Norwich band – now split Bearsuit.

Stylistically, both singers bare a slight resemblance to Icelandic singer Bjork, flitting between gentle sighs and full blown yelp – but a tuneful one.

By the time their 35 minute set is over, the pair have taken the audience on a whirlwind journey – a whist stop tour of many genres.

One mid-set number – Sink – sees the girls repeatedly chant 'I just didn't know what to say.'

It would not be surprising if this loss for words were replicated by their expansive audience.

However, whatever music fans come away from the set saying – it will no doubt be complimentary.
