Mr. Solo Dolo, long a frontrunner in the brooding emo-rap that Kanye West tried out via 2008's 808's and Heartbreak and Drake recently tempered to make it big, didn't take long to change tacks from the pop inclinations of his '09 debut--Man On The Moon II is far too ominous to let the two be grouped together. From the beautifully composed, half-sung odes to kush and loneliness ("Marijuana," "All Along") to the more sparse versions ("Ashin' Kusher," "Trapped In My Mind"), the material on Mr. Rager exudes an overpowering melancholy. Where it could have been formulaic or repetitive, the record leaves you only with a distinctly desolate air, a mood you can't shake like the proverbial dark cloud, an intoxicating view of the dark side of yourself you just can't forget. With the news that he plans to leave rapping behind because he "doesn't get any fulfillment out of it anymore," instead focusing on his new role as frontman of rock outfit Wizards, it's curious to try and discern what his legacy will ultimately be. But for now, Cudi sits fittingly at the pinnacle of existentialist hip-hop.
