AndyU is right: what you want are to create/manipulate different views so that a recording of Beethoven's 5th by Herbert von Karajan and the Berlin Philharmonic is distinguished in some way from a version of the same symphony conducted by Leonard Bernstein and the Vienna Philharmonic. Of course, doing so will probably require you to more neatly tag your files, e.g., "Ludwig van Beethoven" (or just "Beethoven," though what are you going to do when you get to "Strauss?") in [Composer], "Herbert von Karajan" in [Conductor], "Berlin Philharmonic Orchestra" in [Orchestra], and so forth. And, yes, [Artist] should be performers; I myself do a semi-colon delimited list in a predefined order using an expression-based custom field that will build a list based on what performers are present: [Conductor]; [Orchestra] or [Soloist]; [Conductor]; [Orchestra] and so forth, including vocalists and choral or chamber groups.
If you really want to get into the weeds with this stuff, you can set up MCUtils and get mostly standardized data from Allmusic and/or Discogs. Attached is a jpeg of my main classical view populated using the former site. Note particularly my custom field called [AMG Work Name]: that's really handy and can be gotten using MCUtils' amg.pl script for any recording on Allmusic, which has a great database of composers' works. And again, they're pretty standardized, with only occasional hiccups (they just updated their Ravel and Debussy entries, for example, which forced me to go back and change all of my work names, alas). MCUtils does take a little while to set up (and get used to), but once you do it, wow! You'll be swimming in relatively accurate metadata!
Anyway, back to the main point here, the view scheme: note in my view the ordering of the categories: period, composer (with a last name/first name swap), my own personal classical groupings and sub-groupings, the work name (note that I selected "Orchestral," and so whittled down the list of possible Beethoven works; I could have done it ever more finely had I chosen "Symphony" in my sub-group list), conductor, orchestra, and so forth. Such a view takes about 5 minutes or less in MC to set up. And I have others: a "Conductors" view, a "Label" view (so I can see which BIS recordings I have, for instance), "Orchestras" (maybe I DO want to listen to a little Berlin Philharmoniker tonight), and so forth. Really, you're only limited by your tags and by your imagination, which when you factor in the expression language capabilities of MC, can get you just about any view you want.
