Mat - there's a certain joy about Chopin's music, eh? Love it a lot. I'm contemplating purchasing the "complete Chopin" Box CD set ... but it's a little pricey.
I was listening to a sublime recording of Beethoven's Choral Symphony with the Orchestra of the Champs Elysee and Herreweghe, it's a top notch performance on period instruments. I really like it, because there's a section where the second violins and violas have some murderously difficult semiquaver passages (16th notes) and they always get swamped in recordings ... not this one ... nor do the hysterical d major scales he makes them do (with the flutes and piccolo).
