I’ll be honest: I’m not a huge fan of this solo. Mick Ronson was a great guitarist, but he doesn’t seem particularly inspired here. I prefer his solo from the Ziggy Stardust concert movie. There’s more varied melodic content, some really cool sequences, and the big, aggressive bends that people love about this solo are still there.
I prefer to use the bar, but Mick just rocked that bend for all it was worth. However you prefer to tackle it, just go all out. That’s what counts here.
