Re Hiller's E minor first movement, I'd like to second Alan's encomium. This is stirring and masterly music by a composer with something to say. And the Berlin Chamber Orchestra acquits itself handsomely.
During the 1840s, Hiller, like Schumann, was a force to be reckoned with, and still among the more advanced German composers. His first piano sonata is IMHO second only to Chopin's opus 35 in originality among works of its immediate period (the Liszt -- in a class by itself-- comes later). His experiments with mixed meters in the etudes and the second sonata, were well ahead of their time. His second piano concerto, with it's revolutionary treatment of the soloist, showed a way to go, dramatically, beyond the Mozart/Kalkbrenner model. His translation of the Ghazal into pure music expanded the boundaries of prosodic music well beyond existing, typically recitative-derived efforts. We now know that he was an original symphonist as well.
