James Stirling, head of BBC Music & BBC Music Introducing, says: ‘2020 is shaping up to be such an exciting year for British music. BBC Music is proud to play a role in so many of the incredible musical journeys, from YUNGBLUD’s first session for BBC Music Introducing in West Yorkshire back in 2017, to debut Glastonbury performances from Arlo Parks, Celeste and Easy Life on the BBC Music Introducing Stage earlier this year. Congratulations to all the longlisted artists and I am really looking forward to seeing what they have in store for 2020.’
