Over the course of many visits to the Gardner Museum, Finnish pianist Paavali Jumppanen has put together a number of ambitious projects, including complete cycles of the Mozart and Beethoven piano sonatas, the Beethoven violin sonatas (with violinist Corey Cerovsek), and Messiaen’s mammoth “Vingt Regards sur l’Enfant-Jésus.”
But his new project is almost certainly the most unusual. On Sunday, Jumppanen begins a series that brings together solo piano works by Robert Schumann and Karlheinz Stockhausen. Schumann’s “Abegg Variations” and “Humoreske” will be interwoven with Stockhausen’s Klavierstücke IX and XI. Two additional concerts pairing the über-Romantic with the mad genius of the 20th century will follow over the coming year, and it is hard to think of an odder pairing for a multi-concert series.
