A two-hour pan-genre mix presented mellifluously by the improviser Elaine Mitchener bookended by Neil Charles and Micaela Tobin tracks, highlights included the brief interview with the polymath distinguished Columbia professor and composer George Lewis, an influence for instance on the contemporary Glasgow GIO school of free improvisers.

The programme pivots to and from allied areas of the avant garde and certainly is of interest to anyone who likes free improv out of the AACM (Association for the Advancement of Creative Musicians) and adjacent disciplines to have spanned out around the world since the mid-1960s.

It has been a great year for the aforementioned Charles, touring with Anthony Braxton and continuing to build on his already formidable reputation inside the Room to Dream trio. His opening this stimulating show was apt in the circumstances. As for, an erstwhile Braxtonian himself, Lewis, the interview begins from around the 53 min 22 second mark and references 1980s recording Rainbow Family and IRCAM. Listen
