To show what kind of releases I’m talking about see this collection.
Though the Documention states: “Classical” is used here in the broadest sense … the guidelines for track artist only refer to “classical” in the common sense of music composed for the performance by classical ensembles and/or soloists.
What is missing, imo, is a guideline how to credit artists for “classical crossover”, the genre where I would put the collected releases with adding those genre(s) where the music belongs to.
My Personal Opinion: I find this a strange issue. Not everything that uses an orchestra should immediately become classical. Why break a database just to change the tags on some tracks for some users? I worry that “classical crossover” is starting to creep into new areas it doesn’t need to be in.
Many artists experiment and bring in whole orchestras. Or string quartets. Or a classical piano. Or other classical components to their music. That choice of instrument should not change consistent data for that artist.
I think we need to also look outside of MusicBrainz users and see how the outside world credits the music.
Classical Crossover combines traditional classical elements such as operatic vocals, the incorporation of string instruments or full orchestration and applies it to popular music OR the reverse with rhythmic elements, belting or modern techniques used on standard classical repertoire. Many other combinations are possible but the key measure is the blending of both classical and popular styles together to create a new sound. Although it has only recently become a recognized genre in it’s own right, crossover is actually a long tradition.
Pretty obvious examples in my library of the first type are the Hampton String Quartet, famous for their “What if Mozart Wrote…” series.
I don’t have any full albums that I would consider the second type (rhythmic elements, belting or modern techniques used on standard classical repertoire), but a few tracks, such as Herb Alpert’s rendition of Concierto de Aranjuez.
