Even if Boyz II Men's third album Evolution didn't rival II in terms of commercial clout, the group was still inescapable.

Every male urban vocal group that reached the pop and R&B charts were clearly indebted to the quartet's stylish blend of old-school harmony, post-Aretha hyper-vocalizing, and lite hip-hop beats.

The group returned to action in the fall of 2000 with Nathan Michael Shawn Wanya, a nearly eponymous title for their first full-fledged adult album.

And, as adults, they've made sure they're responsible for their own music -- at least one member (usually all) has songwriting credits for all but two of the album's 14 songs, and the group is credited with all but four of the album's productions.

Usually, when a popular group seizes control of their reins in such a dramatic fashion, the result is muddled to say the least, but a remarkable thing happens here -- the group succeeds.

True, they don't expand on the formula they developed on II, but they do fulfill the expectations that album set.

There are no unexpected twists or turns, just the standard lush ballads and swinging hip-hop soul, but it delivers both sonically and substantively.

Not every cut on the record is a standout, but even the average cuts are pleasant, and the best of the batch are either seductive or effortlessly danceable.

Also, the group is beginning to cut back on their vocal histrionics, resulting in a record that is truly their most mature yet.

It might not be their best -- it doesn't have the powerhouse singles of II -- but Boyz II Men make up for it by demonstrating that they can do much of this on their own, and still sound like the standard-bearers for urban soul.
