The Danish String Quartet bring their highly acclaimed Prism project to it's conclusion. The project has been eight years in the making. Now on the fifth and final volume, Johann Sebastian Bach's chorale prelude prefaces Ludwig van Beethoven's String Quartet No. 16 in F major. Anton Webern's early String Quartet, composed in 1905 - and inspired both by Beethoven and Schoenberg - follows, and the programme returns to Bach with Contrapunctus 14 from The Art of the Fugue.
