A mostly female crowd of '80s and '90s kids wore side ponytails, band T-shirts, and neon gear to the Phoenix stop of The Mixtape Tour, a bill that includes New Kids on the Block, Debbie Gibson, Tiffany, Salt-N-Pepa, and Naughty by Nature. The concert, which was held May 22 at Talking Stick Resort Arena, delivered retro hits and plenty of nostalgia.
