The idea that good popular music is all about people ‘playing musical instruments’ is so bizarre. If it were right you could forget about Elvis Presley, James Brown, Smokey Robinson, Frank Sinatra, Marvin Gaye, Michael Jackson, Bob Marley, Madonna etc, etc, etc.
The might be an interesting discussion to be had about the decline of the idea of ‘the band’ in mainstream pop music but this isn’t the way to start it.
