Motley started out more pop than metal; like a heavier, glammed up Cheap Trick (just like his previous band, London). In the early days they covered the Raspberries and solo Alice Cooper (Department of Youth), rather than the Stooges or Sabbath. Sixx AM is not a surprise to me because, while it's slicked up a bit, I can hear Nikki's roots in that band. He's always wanted to be seen as an artist (rather than just a rock star). Brides of Destruction showcased his more rock side, but Sixx AM showcases his pop/artist side. YMMV, as always, but Nikki hasn't strayed from his roots so much as returned to them with this band.
