"Metamorfosi" is the name of the track which opens the extended play by Stefano Rocchi. As a starting point it introduces the main topic of the work; Music After Earth is a journey through a pure electronic flow and evolving dance beats that shape the idea of music evolution, just like our planet evolved as well. "Nature" introduces dry oldschool beats which prepare the listener to the industrialization feel of the following track ,"Cities", well reworked by Dusty with his groovy remix. The EP get closed by the outro "Nothing"; melodies rising from melancholic synths dived in noisy atmosphears kind of call back the listener to an old, natural and simple feel that nowadays human kind has lost in the "evolved" frenetic life.
