Erykah Badu is just about a month into her Out My Mind, Just in Time Tour with rotating opening acts that so far has included N.E.R.D., Bilal, Lupe Fiasco, B.O.B. and Maxwell. But for most of the tour, including the Denver show at the Fillmore Auditorium on June 16, the opening act has been 24-year old Kansas City native and Atlanta transplant Janelle Monae.
