Bach arranged a few pieces of music that were written by Vivaldi. So I search for “Bach Vivaldi”. Two prolific composers surnames; what will I get? Well Roon pretty much nails it. I get one of the Bach arrangements of Vivaldi compositions as the top choice, Vivaldi and a selection of Bachs under Composers, several spot on hits under compositions, and a decent enough selection of albums featuring Bach and Vivaldi. This is excellent.
