In celebration of Earth Day, B.o.B released the E.A.R.T.H. mixtape today (April 22). The title is an acronym for Educational Avatar Reality Training Habitat.

The 10-track project does not have any features. It includes “Flatline,” which the Atlanta rapper released in response to astrophysicist Neil deGrasse Tyson‘s comments about the Earth being round, not flat, as B.o.B argued.

E.A.R.T.H. follows B.o.B’s FIRE mixtape that he released in January. He also released the Live & Direct tape with Scotty ATL last month.
