Teddy Riley is on the comeback tip, and not a moment too soon--what 2006 really, truly needs is more new jack swing, and nobody knows new jack swing like Teddy Riley. The man who put together Guy and Blackstreet is best known for changing R & B forever by producing and/or cowriting all the new jack songs you know by heart (Blackstreet's "No Diggity" and Bobby Brown's "My Prerogative" for starters), plus a few you kinda remember from the club or sound track cassettes circa 1988-1991 (the lesser works of Al B. Sure and Johnny Kemp). Sadly gangsta rap knocked Riley off the charts by the end of the 90s, and the genre that blended hip-hop's lightest touches with R & B's most satiny maneuvers was just a memory. But a few years and multiple lineup changes later, both Guy and Blackstreet are back together and on the road. The rights to Riley's entire catalog--more than 500 songs, including "Rump Shaker" and "How Ya Like Me Now"--were purchased by a publishing company last month, which hopefully signals the dawning of a new new jack era. Guy headlines, Blackstreet plays third, Tony Toni Tone plays second, and After 7 opens. Sat 2/11, 8 PM, Arie Crown Theater, McCormick Place, 2301 S. Lake Shore Dr., 312-791-6190 or 312-559-1212, $44.50-$75. All ages.
