Another chance to hear last Monday's Lunchtime Concert from London's Wigmore Hall. Written for, and dedicated to, Archduke Rudolph of Austria, the B flat trio is the most famous and the largest in scale of Beethoven's works in this form. The Beaux Arts Trio pair it with a work of much chronological debate, the composer's variations on a theme by Wenzell Muller. Beethoven: Variations on Ich bin der Schneider Kakadu, Op 121a; Trio in B flat, Op 97 (Archduke).
