I saw him do a live solo show last year. It was pretty cool and his stage persona was as charming as you’d expect. You should definitely see him if you can.
My favorite song by the band is “Cold Milk Bottle” and The Sunset Tree is a wonderful album.
I think he wrote a 33 1/3 book about a Metallica album that was a piece of fiction and also wrote a novel called Wolf In White Van (great title) that might’ve even been longlisted for the National Book Award. I haven’t read either, but he seems like someone who brings passion and craftsmanship to everything he releases, even if it doesn’t end up being your thing, so I’d bet they’re worth reading. Plus, I think both are quite short.
IIRC, he’s worth following on Twitter, too.
