Imagine going to your favorite musician's show. 

You're in the front row, waiting for them to take stage.

The technicians are vigorously setting up the set. 

There's no guitar, no bass, no drums, no piano.

But you hear screams from fans all around you as one of them spots the musicians coming onto stage.

Here he is; just one man and his MacBook laptop, ready for his concert. 

Welcome to the year 2012 where this is the norm. 

Not only that, but this is the most popular type of show nowadays.
