Robert Worby and Sara Mohr-Pietsch continue coverage of this year's Huddersfield Contemporary Music Festival with a broadcast of American composer and improviser George Lewis's opera Afterword, which celebrates the work of the Association for the Advancement of Creative Musicians (AACM), a pioneering collective of musicians that took root in Chicago in 1965.
There's also music by Jurg Frey, a member of the John Cage-inspired Wandelweiser collective, British electro-acoustic composer Jonty Harrison, and a performance by the Austrian chamber orchestra Klangforum Wien.
And as part of Radio 3's Northern Lights season, a recording of Karen Rehnqvist's Arktis Arktis!, the Swedish composer's orchestral ode to the Arctic inspired by a polar expedition in 1999.
