Running from 7 to 8 November, it plays host to 100 artists from Cardiff, Wales and beyond, making it the only Welsh-centric inner city festival of its kind.
In the past, revellers have caught early gigs with the likes of alt-J, The Vaccines, Wolf Alice and Disclosure before they went stratospheric – and this year should be no exception.

We hope you enjoy!
