HOLLYWOOD — Even after its rollicking “Jungle Love” flashback at February’s Grammy Awards, few fans believed this funk-rocking, sass-talking, prude-mocking septet would rally for a comeback. Set your clocks to oh-wee-oh-wee-oh. The Time is now. The Minneapolis funk group that Prince assembled in 1981 is in the midst of a 15-show live run that includes a stop today at Freedom Hill Amphitheatre in Sterling Heights. A fifth album is nearly complete.
