How many versions do you have?

If the question is how many versions of the same piece, I have 6 versions of Bach's "Mass in B Minor". The one I go to is the Herrewegge, even over the vinyl.

Same as Kal...
Several versions of Erik Satie's Gymnopedies/etc...
7-10 versions of Bach's unaccompanied cello suites, among my favorite being one played by Edgar Meyer on the double bass.
3-4 versions of Holst's Planets (my "go to version" being Mehta/LA on Decca)
Several versions of Chopin's Preludes - haven't figured out, even after 20-25 years of listening to and playing these, which one is my go-to version.
Several versions of Rachmaninoff piano trios.
Lots of versions of several or all Beethoven Symphonies
And I have seem, without trying, to have come up with a bunch of versions of Dvorak's 'New World' Symphony, a couple of Mahler symphonies,

and, last but not least... I must have a dozen different recordings of Jimmy Smith playing "The Sermon".

Chasmal,

I have about three versions on LP and around five or six on CD. I too, like the Herrewegge a lot for the performance (the recording is a touch sibilant, but it is pretty good too). I also like Perlman, and for something really different, the Rifkin (one singer per part).

I have silly number of multiples for Beethoven's late piano quartets (I like the Vegh Quartet, Quartetto Italiano, the Hollywood Quartet), Wagner's Tristan und Isolde (amazingly, I like Domingo), and the Bartok String Quartets (I like Takacs Quartet).

ON Dvorak's 9th Symphony, I highly suggest Bernstein with the Israel Phylharmonic. The 2nd movement is the most lyrically intense performance that I have heard. . . just do not expect an 'audiophile-grade' recording. . . get this for the music, not for the sonics. . . Besides, Lenny B. is one of our great lost Titans! G.

Over 20! :)

Mh favourite is the one with Carmigniola!
