B.o.B Completes His 'Elements' Project with New Album 'Ether'

After dropping mixtapes Water, Fire, Earth and Air, B.o.B is back with a full-length album to round out his Elements project. Titled Ether, the LP marks the rapper's first studio album since Underground Luxury in 2013.

"Ether refers to the etheric realm in which all matter and all energy move through," he tells Fuse, explaining that his album represents the fifth element. "A lot of the Eastern traditions and beliefs recognize chi, the energy that you can't see. It's the unseen."
