As Fat Mike put it, this was "the album to change everything". This ushered in the "modern" style of punk, which deeply influenced modern bands like [insert almost any punk band from the 90's SoCal scene].
The exuberance of this release is kinda tuff ta' blow off. Contains the superior original version of "21st Century Digital Boy" plus 16 more crucial cuts. A barrage of melodic, hyper-overdrive.
