The whole thing with Megadeth is really a damn shame.
My story becoming a fan of Megadeth starts much later than I'm sure some of you. I knew of them in the late-80s and early-90s. I saw the videos from Countdown to Extinction on MTV, dug em, but never really pursued buying their records. But then in 1998, I dug what I was hearing on Cryptic Writings. Heard Megadeth was playing Ozzfest with TOOL, and so I went out and bought Cryptic Writings and TOOL's Ænima. Enjoyed them both and became a fan.
Megadeth was good at that show, but there were technical problems, so what I remember most is Dave having a fit on stage and either smashing something or kicking something. It's vague, but I remember it. I don't remember TOOL's performance really, and all I can recall from Ozzy was there being a sheer curtain around the stage, and him coming out wagging a hose like it was his penis. LOL.
Anyway, five years later, I get married to a HUGE Megadeth fan. I start getting into the catalog, and I became a massive fan. We saw Megadeth's first show back in 2004 (I think it was, if not, it was the first tour), and I've been invested in them ever since. And honestly, after Endgame, I've just been disappointed. Some records were good, some were not, but Dave can't sing, all the songs are dropped and sound like mud. Frankly, Megadeth should have been finished a decade ago. But Dave soldiers on, his son Justis keeps putting him on the road, and really, Dave Mustaine needs to either hire a better singer, and put the songs back in the original key, or hang it all up.
Megadeth is limited because Dave Mustaine can't sing. If all he had to do was play guitar, it might be different.
The last two albums are certainly good. I prefer Dystopia, but both are good. But while I am used to the rotating members thing, it has really become stupid at this point, IMO.
