John Shea presents a concert celebrating some of Prague's most famous composers. German violinist Christian Tetzlaff contrasts the ethereal sonata of Janacek with the child-like simplicity of Dvorak's Sonatina. He is joined by his friend and fellow countryman, pianist Lars Vogt. Janacek: Sonata for violin and piano Dvorak: Sonatina Brahms: Sonata No 3 in D minor.
