Come behind the “Velvet Rope” and “Cool It Now” with two Black music legends. Janet Jackson and New Edition will be bringing their “Rhythm Nation” together for a night of “Escapades” and fun, “All For You,” Louisville. “Is This the End?” Not at all. It’s “Crucial” that you make it to this show and “Runaway” with Ms. Jackson, if you’re nasty… and the original “Boys To Men,” New Edition.
