The "superband" concept of the sixties is dead and has been for a long time. The equivalent music of the times is usually done by electronic producers, who are much more plentiful, competitive, and underground; record labels prefer to invest in huge pop star acts rather the up and coming musicians. Consider that over 90% of radio is owned by Clear Channel, so the variety of music most people who are not hardcore listeners has been substantially decreased. Finally, since access to music from the past is easier than ever before (remember that in the age of vinyl records represses were rare, so people would only have what was available to purchase at their disposable), most people prefer to continue to listen to the stuff they heard in their teens rather than continue to investigate different tastes.
