Even without a single guest, Janelle Monáe’s sophomore album, The Electric Lady, was probably destined for spectacularity. But the record, dropping Sept. 10, will nonetheless feature Prince, Grammy-winning jazz artist Esperanza Spalding, Miguel, Big Boi, Cee Lo Green, Solange on the title track, and, of course, Erykah Badu on “Q.U.E.E.N.â€Â Pitchfork has the full track list.
