I saw Slayer open for W.A.S.P. in a small town in Texas on the Reign in Blood (Def Jam) tour. Slayer was out of hand, I remember blacking out from being crushed in the mosh pit. And then everyone left when W.A.S.P. came on. Blackie Lawless was so pissed! It was the end of the bullshit hair-era and the dawn of thrash!
