Faith No More (headlining, saw them open for Metallica and GnR in 1992)
Alice In Chains (only saw them open for Ozzy in 1992)
After over 20 years of going to concerts, i've seen just about every band headline that i've wanted to. That's why I put FNM and AIC on my list, i've only seen then as the main support band. I know why FNM has never happened but I have no clue why it is that I keep on missing AIC when they tour?
