Maybe everyone should use the Ying Yang Twins' strategy of explaining what their plans are before the album even starts. On "Intro," the pride of the Dirty South explains how on the first half of "Chemically Imbalanced" (TVT) they plan to appeal to their old fans and on the second half they plan to try something new with the help of Wyclef Jean.
Then - this is probably the more important part - they do exactly what they said. The first half picks up where "Salt Shaker" left off, with more party music including "1st Booty on Duty" and "Jack It Up" and a slow jam, "Take It Slow." The second half is a little edgier, as the first single "Dangerous," with Wyclef Jean, shows. The spare bass line (not to mention the bit from Hall and Oates' "Maneater") leans more toward Gnarls Barkley than Lil' Jon.
The Ying Yang Twins strategy is refreshingly straightforward, giving the fans what they want while giving themselves room to grow. ("Chemically Imbalanced"; grade: B-)
