So, here's a thought. The drummer and guitarist in Megadeth leave. To me, the best era in Megadeth is when they released "Rust in Peace" in 1990. That release is simply awesome. Marty Friedman played guitar and Nick Menza played drums on that release. The speculation on sites like Blabbermouth.net is that Friedman and Menza could return to the band. That would be extremely awesome. Maybe. It would depend upon if they could come up with material as awesome as the material from "Rust in Peace." Here's a video of Nick Menza playing along to "Holy Wars." The sick thing about this video is that I could hum along the words, even though you can't hear Dave Mustaine singing.
But then again, I love this entire album.
