A native of Helsinki, pianist Matti Raekallio has established himself as a prominent concert pianist with an enormous repertoire, including more than 60 concertos. He made his American debut at Carnegie’s Weill Recital Hall in 1981, and his engagements have included many of the leading music festivals, such as Berlin’s Klavierforum 1999, where he presented all 10 sonatas of Scriabin in one concert. Mr. Raekallio’s solo recitals often concentrate on a single composer and genre, such as the 32 Beethoven piano sonatas, which he has performed as a series eight times (including a sold-out marathon at the first Irving S. Gilmore Piano Festival that was broadcast on PBS). He has made some 20 recordings, most for the Ondine label (including a three-disc series of complete Prokofiev sonatas). Mr. Raekallio joined the faculty at the Hochschule fuer Musik in Hannover, Germany, in 2005. Prior to that, he became full professor at the Sibelius Academy in Helsinki, where his teaching work had started in 1978. He studied piano in England with Maria Diamond Curcio; in Austria, at the Vienna Academy of Music, with Dieter Weber; and in Russia, at the Leningrad (now St. Petersburg) Conservatory. Mr. Raekallio is a regular juror in major international competitions.
