Worlds collide in this scintillating programme, devised by Wigmore Hall’s Composer in Residence Julian Anderson and EXAUDI’s director James Weeks: medieval and modern, sacred and profane, European and Eastern.

12th-century Parisian polyphony elides with the drone-rich imagination of Giacinto Scelsi; Heinz Holliger’s fascination with Machaut can be heard in the luminous Angelus Silesius settings of nicht Ichts – nicht Nichts; and the intricate rhythmic world of the Ars Subtilior finds a parallel in the ardent, tangled vocality of Finnissy’s dramatic Kelir.
