Megadeth, Sunday March 6th at Grey Eagle Casino.
with Suicidal Tendencies, Children of Bodom and HAVOK.
I've seen both Slayer & Megadeth in the last few years, so I'll probably pass on both. But given the venues I'd lean towards Megadeth/Children of Bodom if I had to choose one. But Testament opening for Slayer ain't too shabby either.
