When B.o.B's May 25th mixtape hit the 'net back in February, readers and staff agreed that Gladiators was a cut above the rest. Today, slowpokes who still have yet to listen to the project can finally hear what the fuss is about. On this slow-burning banger, heavyweight producer The Alchemist serves up a densely-layered instrumental fraught with tense synths and glimmering piano riffs as B.o.B and fellow buzzmaker J. Cole suit up for battle. The rappers aren't fighting amongst themselves – on the contrary, they seem determined to take on the whole damned industry. The headliner comes with even more intense flows than usual, while Cole keeps things a little lower-key, spitting guest bars that drip with steely determination. Needless to say, the record should have readers cheering just like spectators at the Colosseum. If you're a Bobby Ray devotee, you'll be happy to hear that the album release date cited in the title of his latest mixtape has already been rendered incorrect. Say what?! That's right: the artist's debut set, The Adventures of B.o.B, has been pushed ahead to April 27.
