I think the quartet form is an interesting one for Rock and Jazz fans as it also has the (usual) four artists playing against/with one another.Quartets are one of the backbones of Classical music.
Schubert quartet: "Death and the Maiden"Beethoven "Middle Quartets’ Rasoumovsky #s 7,8,9 (there are box sets of Beethoven quartets on Amazon for like $17 for all of them. Great deal. (by Hungarian Quartet, or Tokyo Quartet) Actually cheaper to buy the whole box. I JUST BOUGHT both of the above in the middle of typing this.
I actually just ordered three Beethoven Quartet complete sets and a complete set of Beethoven sonatas. 7,7, and 9 (the nine includes Bartok Quartets, not for the fainthearted!) , sonatas, 10CDs. so 34 Classical top notch CDs off Amazon for $75. shipped.(One odd thing typical of Amazon, others like Emerson version of Beethoven Quartets, I bought before for $15 are now $35..)
One of the lovely things about Classical is interpretation can change the whole thing. So For the likes of me, having five different sets of Beethoven quartets is a good thing.
