i heard tchaikovsky's 5th sympony on the way into work this morning and i can't stop humming it. this particular recording is by the leningrad philharmonic and was recorded in 1960. the 5th symphony has a number of very catchy themes that quickly burrow into your head and just get stuck there. every time i hear this symphony, i love it more. it has even eclipsed my appreciation of his 6th symphony, though i don't think it'll ever surpass his slavonic march.
