On 21 November Sigvards Klava and the Latvian Radio Choir will revisit Anders Hillborg’s choral showpiece Mouyayoum at a concert in Augsburg.

A study in ever-shifting tone colours, Mouyayoum draws its inspiration from overtone singing, creating an intricate and luminous tapestry of sound across its 13-minute span for sixteen-part mixed choir. Composed in the mid-80s, it is Hillborg’s most performed work, a mesmerising choral tour de force, and has been widely recorded.
