Our cover star this June is a unique British artist: the cellist, composer and singer-songwriter Ayanna Witter-Johnson. With her high-level grounding in classical composition and an ear for myriad musical influences, she has a style like no other. On page 28 she speaks to Toby Deller about her upcoming plans, which include a new release this month and a performance at the Edinburgh Festival with the LSO Percussion Ensemble in August.
