Live recordings always suck compared to actually being there in real life. When you hold live recordings to the studio recordings inevitably they aren't nearly the quality. If they were no one would bother with going to a recording studio. But it should go to show you that music is a lot of hard work, one that very few people appreciate. I have seen Megadeth MANY times live and never once did I think it was a bad performance.
Um yea mustaine sang for metallica, it was just before they made their debut album, Kill em All. and if you knew anything about thrash metal ud know that. and no s**t that was james singing. like i said before, it was when they were doin gigs when he sang for metallica...it was also when metallica was good.
If you think this is bad, go to livemetallica.com and download the free 1982 concert. That has Mustaine sounding really bad!!!!! Wonder if Metallica released it for that reason?
