Megadeth's best album! Trash and ultra-fast technique, this album blows everything in its path and I still wonder how we do not talk more today. Difficult to access at first listen, this album is marked by a fabulous job in guitars, manhandled up by Dave Mustaine and Marty Fridman at their best. The rhythm section led by Nick Menza (drums) and Dave Ellefson (bass), is also breathtaking. A must-have !!!
