Loop grid query need more.

I made a page for music label.
I create a template for artists page inside of it I put a loop grid with last release of artists. And I put query: category/release.

Now I cannot use same template for all artists cause release will appear not separated by artists.

It will take all release category and not just the release of single artist.

My solution was duplicate template and change query in all template and give singolar post instances but is crazy thing. I suppose it will be some easy way. #loopgrid
