Book excerpt: Most concertos are difficult, and opportunities to play these great works with orchestra are very rare. Intermediate pianists can now experience the excitement and beauty of performing themes from nine favorite piano concertos, at their own level, with orchestral accompaniments on the available General MIDI disk (Alfred item 18215). The varied styles of Beethoven, Haydn, Mozart, Rachmaninoff, Schumann and Tchaikovsky are respectfully represented in arrangements that beautifully get to the "heart" of each concerto.
