Iamsu! has modest ambitions. "I just wanna chill, I just wanna smoke/ Slide through the city, go see my folks," he harmonizes over "Girls." The Richmond, Calif. rapper isn't vacuous; on the title track he details his troubled childhood. But he sounds at ease with simply making a fresh beat and rhyming over it. Amidst the mellow vibes, it's easy to overlook his weaker moments -- and at 18 tracks plus bonus cuts, there are a few -- and enjoy pleasant surprises like a sample of Jazzanova's "No Use" on "Ascension," and an inspired rework of Aaliyah's "One in a Million" into "Stop Signs."
