One interesting message is that music that is recorded and music that is performed have diverged rather dramatically. That has major implications in an era in which many artists have adopted a strategy that making their living is going to depend on live performance revenue, and recording is more of a loss leader. The major shift in the Beatles' musical innovation from bubblegum band to innovative genius did not occur until after they decided to stop touring, and spend their time in the studio. In the show, the Beatles are complaining that they cannot hear themselves over the screaming of their hyper-estrogenized tween following. Not mentioned is that the concert sound technology available early in their careers was dismal, but nonetheless, the real impetus seems to have been that they could do things with their recorded music that was not possible in live performance. Contemporary real time processing has enabled some studio effects to move to the stage, but unless the performance becomes just singing along with a recording (albeit one consisting of loops and huge samples triggered by keyboard presses or stomp boxes), a form of advanced karaoke, there are always going to things that will be better suited to recording. I was never interested in seeing Kitaro running around a stage full of computer gear in a live performance, but his recordings were worth hearing. If recording becomes a truly fruitless endeavor, it may change the character of the music available in mass culture.
