Completely buttfucks their debut in every possible way! Songwriting's better, riffs are heavier and more varied, production's seen a MASSIVE boost in quality, the guitar tone's got some nice crunch to it (reminiscent of George Lynch's tone on Under Lock and Key and Back for the Attack), and Eizo Sakamoto's singing is less amateurish.
