Blast is inviting 13-19-year-olds to design a piece of album artwork that includes a portrait of some kind, for one of three unsigned bands they are currently featuring (Ed Sheeran, Rizzle Kicks and El Policia). Six winners will be selected to attend a two-day masterclass in March, where they will work alongside leading artists, photographers and music industry professionals to create brand-new publicity artwork.
