Q: Certainly this 2nd symphony should have shown the world Raff was a rising star. The opinion of his contemporaries that Raff was one of the greats is borne out here. The 2nd movement is so lyrical, it is worth the price of the disk by itself. The orchestra, though perhaps not well known, gave an outstanding performance. It is a pity that my CD from Amazon contained no program notes unlike what another reviewer reported. However, I'm very pleased with this very fine disk and strongly recommend it to anyone who enjoys hearing Romantic era works that ought to be better known!
A:
Positive
