Sven-David Sandstrom is Sweden's foremost composer of choral music. Paul Guinery explores Sandstrom's highly evocative choral music in performances by some of Sweden's finest choirs. The climax of the programme is a recording of Sails of Longing, a 40-minute work for male voice chorus and orchestra, commissioned by the Orphei Drangar Choir. The Swedish Radio Symphony Orchestra is conducted by Manfred Honeck.
