I've recently been reading Chopin's biography, and as I'd expected, the bio mentions Chopin's musical friends while in Paris (Franz Liszt, Hector Berlioz, Mendelssohn etc.). I also came across a name I'd never heard of before: Friedrich Kalbrenner, a pianist. According to the biography, Chopin thought very higly of Kalkbrenner, and Chopin even said once that he 'felt unworthy of untying his shoelaces'.
I grew interested about this guy, so I looked him up on the internet, and was astounded to find that he had written more than 200 piano works, piano concertos and operas of which a few have ever been recorded. He was also the first pianist to introduce rapid octave scales into the piano repetoire.
I think it's time to revive Kalkbrenner on Youtube! I'm currently transcribing his Brilliant Variations on a Mazurka by Chopin (Op. 120), and hopefully I'll finish it someday.
