I recently watched a documentary movie on Netflix called The Wrecking Crew about a group of studio musicians in LA in the 50s, 60s and 70s that did the instrumentals on just about every hit record that came out of LA during that time period. I can remember going to concerts in the 70s and 80s and the bands never sounded as good live as they did on vinyl. The line was that the rudimentary sound systems and single takes relative to studio recordings was the reason. No. Its because there were different, way more talented musicians playing on the recordings. This is a really cool movie for all of us who lived through that time period and if you haven't seen it, I recommend it. They have a website too (who doesn't?)
