The Oxford Alternotives are back for their ninth consecutive year at the Fringe. The 15-strong ensemble is renowned for their creative arrangements and close harmonies, performing everything from pop to house to RnB to old-school classics. Just in this past year, they released their EP Revolution, performed on BBC Ones Pitch Battle, and were UK Finalists in the 2018 International Championship of Collegiate A Cappella. With a stylish set list, slick choreography and inhuman beatboxing, this show will charm anyone from die-hard a cappella aficionados to even the most sceptical of Fringe visitors. ***** (BroadwayBaby.com).
