Jez Nelson presents a double bill from Bath International Music Festival. Cuban pianist Omar Sosa appears with an intriguing trio featuring conga player Miguel "Anga" Diaz, stalwart of many of the Buena Vista Social Club albums, and the Tunisian oud player and vocalist Dhafer Youssef. And Finnish quartet Ilmiliekki make their first major appearance in the UK. The oldest member of the band is barely 26 years old, and their debut album March of the Alpha Males was one of the discoveries of last year.
