I've never quite got the point to a rock hall of fame, but as long as there is one, it's great to see Metallica and Run DMC inducted. And as a longtime Metallica fan - now officially stretching to half my lifespan - it's a thrill to see Jason Newsted playing with them again. I have no idea if they have all made their peace with one another, healing the longstanding wounds that led to Jason's departure and Metallica's near breakup in 2001, but the fact that they can play together for one evening is very nice.
And, hey, for a band notorious for burying the bass guitar in their album mixes, it's a rush to see two bass players on stage. I wonder why more metal and rock bands don't use that? Most likely because the rhythm guitarists are essentially playing bass with their low strings. But spend some time with the Miles Davis fusion albums, and you'll come away with some good ideas.
Pity the YouTube videos are such low quality, but I'm hopeful that better versions will later emerge.
