B.o.B. has been periodically releasing mixtapes this year named after the four classical elements. The series may or may not have something to do with the rapper's belief that the earth is flat. To date, he has released WATER, FIRE, & EARTH. Monday morning, he completed the quartet by sharing AIR (Art Imitates Reality).
AIR is comprised of 11 tracks. It is entirely self-produced. Stream the tape, share your thoughts in the comments, and listen to the rest of B.o.B.'s elemental mixtape series, which has been well-received.
