There is a documentary called "Hired Gun" on Netflix. It is a general documentary about how music is made. Hired Gun is the term assigned to the musicians that play in a band, and in some cases sing in the recording studio, that are just hired by the "Star" and unfortunately go from playing for millions of people on tour one week to being homeless the next.(all while the star rolls in the big money) It is a very eye opening documentary about how most of the players that record the albums aren't even in the band!!!! What blows my mind is that some of the songs are even sung by and recorded by people not in the band!!!! You just thought Ted Nugent sang Strangle hold. This documentary covers a huge array of musical genres. (even the Ghost busters theme) Billy Joel.... Country....MoTown...Pop...Rock...Heavy Metal. A hand full of "Studio Musicians" are the ones who have recorded most of ALL the music people listen too. So when you buy a CD to listen too, you aren't even listening to the band you thought you were. If you like music WATCH IT!
