associating multiple artists with a product

Can anyone suggest a way to associate multiple artists with a single product.

There are way too many collaborations going on these days.

I modified the recording label sidebox into an artist sidebox...and it would be ideal if I could just list individual artist names in record artists.
Say I have albums available from these two artists...
taylor deupree
richard chartier

then I have a collaborative album where they go by..
richard chartier + taylor deupree

Now if I were able to associate multiple artists to a single product when either individual name was selected from the artist sidebox the collaborative album would appear.

This would also be ideal for compilations etc.

Any ideas, suggestions, that could get me pointed in the right direction.

Thanks and all the best,
Jeremy
