Mauricio Kagel bends time in a curious work for piano and metronome and evokes Beethoven's ghost in one of the most unusual homage pieces of later years. We hear Silvestrov's nostalgic epilogue and Saint-Saëns' second string quartet, a work composed at the end of the first world war when the composer was in his eighties, a work which at times sounds like Beethoven or even Haydn.
