If you haven't guessed by now, Boyz II Men are back. After falling off the music map a few years ago, the most commercially successful R&B group of the '90s (and arguably of all time) is embarking on an ambitious branding tour to promote their previous body of work albeit minus the heavy-bass baritone of Michael McCary.
