Dionne Warwick and the young Swedish-born singer Emilia Martensson open this year's Cheltenham gathering, which rivals the London Jazz Festival as the major event in the UK's jazz calendar.

Friday's line-up includes cool songstress Madeleine Peyroux, rising star Laura Mvula and the acclaimed Norwegian saxophonist Marius Neset.

Over the weekend, Ravi Coltrane and star vocalist Gregory Porter are among the picks – Porter delivers a talk on Finding Your Voice on 5 May – and closing highlights include Gary Burton, a tasty pairing of Polar Bear and Roller Trio, and Van the Man to finish.
