Souza was right about one thing, Louis. Canned music would eventually reduce the number of trained musicians with technique. Fortunately, it inspired enough talent working outside usual technique, thus we have the variety we do today (think blues, jazz, rock and roll). In fact, it increased the fan’s need for live performance, which is why many artists rely on concerts over record sales. I can imagine why Souza was worried, but I think he might approve of what resulted in terms of influences and styles (can’t imagine what he’d think of vocal enhancement, though). Thanks for the post.
