I am not into classical music, but I think there are similarities for fans of jam bands especially the grateful dead. Ive never heard a group so passionate about specific versions of song depending on the date/location.

I feel UI designers could make something work but its such a niche group of people its hard to spend resources designing and maintaining a catalog of recordings of different versions of the same song.

Come to think of it, Phish or Grateful Dead live shows have some overlap, but that's more about recordings on different dates by the same artist, while classical adds different artists, or sometimes the same artist on different dates, or sometimes the same orchestra but a different conductor, or...

But yes, that's the closest I can think of, but I think it's a smaller niche even than classical music.

Jam bands may often have varying lineups / guests, which complicates things more than just different dates.
