this was a series first broadcast in the early '90's, back when Channel 4 made interesting programmes.
I assume this is a transfer from someone's home VHS recording.
Although it's aimed at a general audience and isn't a how-to, nut and bolts analysis, there's a lot of interesting stuff to watch
part 2 covers Indian music, Andalusian flamenco and salsa - http://vimeo.com/album/2818579/video/37583311
