I played Under the Influence more than any other thrash album in the late 80s. Megadeth, Anthrax and those ageing stadium rockers (you know who I mean) may have sold more records than Overkill, but the East Coast guys were always lurking in the shadows, waiting to claim the crown. It's unashamed heavy riffage that oozes energy from every overpowering bass strum. Wicked thrash guitar breaks and some frantic drumming from the new guy back it up. Bobby 'Blitz' Ellsworth screeches his impassioned heart out. What's not to like?
