Yes those are a good example of (something like) concerts being the best business model for a group of artists now. I just find it funny how we all have witnessed the success of so many different business models, and then for someone to say that only one is possible.

And that type of layered electronic music could mostly be reproduced "live" if the artist was up to it, by playing live on keyboards and making loops then mixing them up with prerecorded samples. Of course, most DJs would rather just push play when they have live shows because it most take a lot of practice to master live looping. I saw Justice live recently and they were very good at pushing play.
