During the 1950's, 60's and into the 70's, one sub-genre of the pop/rock scene was the instrumental. Instrumentals, both rock and pop, got lots of coverage on the radio and in albums, a few even making the top 10 in the Billboard Charts, and more than just a few artists just about specialized in them! Of particular interest to readers on this message board was the fact that a significant number of these instrumentals where themes from the movies and TV shows. Alas, it seems those days are gone, and I sure do miss them. Does anyone have an explanation or a theory as to why instrumentals lost their popularity?
