I never warmed to ZZ Top (the "showmanship" always put me off, and when I saw them on television acting as if they were the mos hilarious people the world had ever seen because the only member in the band called 'Beard' was the one who - get this - didn't have a beard, I would have cheerfully shot the lot of them), *but* Billy Gibbons is a very gifted player. I'm always impressed in interviews too how many younger names on that general scene have such good things to say about how he complimented them or mentored or encouraged them: you can always tell someone is secured in their own ability by the fact that they want to share the joy, and help others make it too, rather than talk themselves up at others' expense.
