All Time Low began as windswept emo-pop faves. They’ve taken giant steps towards adulthood, and Last Young Renegade shows the lessons learned. “Life of the Party” flicks the light switch on and off, exposing crumpled tinnies and bodies. They bid farewell to youthful habits on “Nice2KnoU” and cut off bad relationships on “Drugs & Candy”. Their horizons expand with help from Tegan and Sara (“Ground Control”) and the uplifting “Afterglow” shows the band is here for the long haul.
