Students suffering from “99 problems” can ease their pain with a healthy does of rap and soul tomorrow evening at the Schottenstein Center.

In celebration of their upcoming new album, “Unfinished Business,” (to be released Oct. 26) Jay-Z and R. Kelly have teamed up for a two-month, 40-city tour – fittingly entitled “The Best of Both Worlds.”

“It’s like mad scientists in the basement,” Kelly said during their press conference for “The Best of Both Worlds” in January. “Jay is real creative, I’m real creative, and you want to get together and mix potions.”

Singles from “Unfinished Business”, “Big Chips” and “Don’t Let Me Die” will be added to radio rotation Monday.
