With a mix of bracing riffs, deep grooves, soulful vocals and swirling harmonies, "Fifteen" which was originally issued in Japan last October showcases the guitar-driven, bluesy-rock with the hard edge the band is known for. Co-produced by Nelson with Mike Plotnikoff and Paul DeCarli, the album is filled with highlights like "Out Of Line" as well as "Sorry", a ballad co-written by Marti Frederiksen (AEROSMITH).
