When Norwich duo Let's Eat Grandma - aka best pals 16-year-old Rosa and 17-year-old Jenny - dropped their debut single 'Deep Six Textbook' earlier this month, they didn't quite #breaktheinternet Kardashian-style, but they did cause a pretty hefty stir among the web's indier quarters.

Instantly transporting you into the pair's magical, mystical world of witchy, wide-eyed imagination laced with vocals straight out of a twisted fairytale, it introduced us to a unique pair with their own singular and fully-formed universe. Now, the pair have dropped 'Sink' - the B-side to their debut - and it shows an even more intriguing side to the two. Still rooted in the strange beauty of their first offering, it also adds a slight r'n'b beat to proceedings with Rosa and Jenny spitting lyrics over the enveloping melodies behind them.

Unsurprisingly given the excitement around these two, they've already sold out their forthcoming headline show at The Forge in Camden. Keep your ears peeled for further dates and let the countdown to their inevitably incredible debut begin.

Listen to 'Sink' below.
