Dvorak's Sixth, in D Major has fast become my favorite of the Dvorak symphonies, even eclipsing No. Eight, which I thought would NEVER happen, LOL! I have heard that Dvorak wrote it as a 'thank you' to Brahms, for being instrumental in getting Dvorak a contract with Brahms' own publisher Simrock.
At any rate, there are some Brahmsian influences in the work, but all in all, it's just pure Dvorak. And as another poster mentioned: the Furiant by itself is worth the price of admission to this delightful work.
Several others: Kalinnikov's First Symphony--very Russian, very fascinating.
Glazunov: Fifth Symphony. It has a very spectacular 'drums and trumpets' finale.
Walton's First Symphony: Not as often heard as it used to be, but a monumental work from one of my very favorite British composers.
