Just in today, Wagner Fragment from Parsifal for Cello Quartet.

Parsifal is an opera in three acts by Richard Wagner. It is loosely based on Wolfram von Eschenbach's Parzival, the 13th century epic poem of the Arthurian knight Parzival (Percival) and his quest for the Holy Grail.

Wagner first conceived the work in April 1857 but it was not finished until twenty-five years later.
