Mahler

concert on R3 tonight on this very topic:

Thomas Dausgaard is a conductor who delights in exploring the complex roots that feed into composers' music. In this concert he brings together 3 composers with an influence of Jewish music alongside the renowned Klezmer band, She'Koyokh.
The first half begins with Bernstein's Candide Overture and a rare chance to hear the cello work Schelomo by Bloch: cellist Jian Wang joins the orchestra.
And in the second half a performance of Mahler's First Symphony is introduced by a prelude performance of Jewish folk music by the band along with the BBC Scottish Symphony Orchestra - to hear what resonances emerge.

This stage performance of Resurrection (including a performance of Symphony No. 2) has a team of UN relief workers unearthing a mass grave in real time. Esa-Pekka Salonen conducts. Naturally it's divisive, but wildly ambitious and unflinching as well.

Streaming live right now, but hopefully will be available for rewatching on Arte's site:
