There are ways of making Particles that point to the various chapters inside of MKV files. Each particle then becomes like a song. There is a utility that I haven't used yet called MCUtils, which includes a particlize function, designed to look up chapters in a database and then build Particles for each song based on the database.

On the other hand, if you only have a small number of concerts (like me) you can manage them a different way. I use MakeMKV to make one (or a few) large files for a concert. Like you said, these MKVs have chapters inside them that usually correspond to each individual song. I then use MKVToolNix to split the large MKV into individual chapter MKVs. So I end up with one MKV per chapter; essentially one MKV per song.
http://www.fosshub.com/MKVToolNix.htmlThen I import all of the small MKV files (that were split by MKVToolNix), which are sequentially numbered (because MKVToolNix numbers them). I usually have to adjust those numbers to correspond to chapter numbers, but it's very easy. Just a tiny bit of subtraction or addition using an expression and I can have the [Track #] field be correct. The hard part is then naming each chapter for the song it contains. I usually use an online listing of the song names along with chapter numbers and then cut and paste from a web page into MC's tag editor, or it's main listing in the [Name] field.
This is tedious, but it doesn't take all that long. Like I said, I only have a small number of concerts, so it wasn't a great deal of effort for me. Plus I like organizing things and I like MC's expressions, so it was kinda fun in a weird way. If you have a lot of concerts this probably isn't practical for you.
I then have a View built called Music Videos. It lets me filter by Artist and/or Album (Concert) and see thumbnails of all of the songs, which is nice. See attached screen shot.
