"It is with deep regret that we confirm the news that Cocteau Twins, at the request of vocalist Elizabeth Fraser, have cancelled the planned reunion performance at this year's Coachella Festival on 30 April. No future plans for any reunion are currently being made. Our sincere thanks and apologies to all the fans and media who wrote to us expressing your enthusiasm and support."
