At just 17 years of age, they've taken the music world by storm.

And now Norwich duo Rosa Walton and Jenny Hollingworth, who perform as Let's Eat Grandma, are getting ready to perform on Britain's biggest musical showcase - Later...With Jools Holland.

Rosa Walton and Jenny Hollingworth, who attend Access to Music college in Magdalen Street, will perform on the BBC Two show on Tuesday.

The appearance follows a massive year for the pair of multi-instrumentalists.

Not only have they thrilled crowds at the Festival By The Sea in Margate and the Latitude Festival near Southwold, but they've flown across the Atlantic to take the stage at the Pop Montreal Festival in Canada.

Rosa said their success sometimes seemed difficult to comprehend.

She said: 'It's kind of hard to process it before you're actually there. It just seems so far away from what we've been doing today at college.'

This weekend will also see the pair launch a new tour with a show at Norwich Arts Centre as part of Norwich Sound & Vision.

Rosa and Jenna met aged four at their infant school and have been inseparable ever since.

Let's Eat Grandma was formed in 2013 when Rosa was given a second-hand acoustic guitar for her birthday and Jenny started learning the ukulele.

Influenced by jazz and classical music and a desire to break out of the traditional pop formula, they started composing their own unique compositions and their repertoire of instruments has expanded to include the saxophone, piano, mandolin, drums, synthesizers, harmonica, recorders and whistles.

In the lead-up to Latitude, Jenny said: 'People should not expect anything; we don't want to put a label on our sound as we take influences from a variety of artists.

'But we have lots of musical influences from the K-pop genre and influences outside of music like horror films as well as our own dark hobbies.'

Other guests on next week's show, which starts at 10pm, will include St Andrews-raised singer-songwriter KT Tunstall, Alabama band St Paul & The Broken Bones and five-piece vocal harmony legends The Temptations.
