Hot Shoe and Andersen Book
My two cents:
I'd say Ian A's Burning the Tables book is a must read
(only one of many, maybe 7 or more) for newbie serious players.
Hot Shoe I liked. I think it's great for background info,
visuals, and such. Though as production quality it's not that
great, but that's to be expected it's not a big budget thing.
And I would definitely use it to inform students or perhaps
interested but skeptical friends/ relatives and such.
Oddly, I found the interview with Ian Andersen in the film
rather uninspiring. But who knows, that may have been on purpose
as part of his cultivated enigmas regarding identity and
persona.
