I cannot remember where I bookmarked this article from exactly, but this is an article from West 86th about a 1967 film collaboration between Jim Henson and Raymond Scott which kind of blew my mind.
I'm a big fan of Raymond Scott and have always felt like the larger music community outside of archivist-minded record collectors and purveyors of the oddball should really be more acquainted with him as he invented a good amount of the technology and methodology that pre-date electronic music. Most of the modern interest hasn't ventured beyond Reckless Nights and Turkish Twilights. All that said, that compilation was my introduction as well and most of my ventures beyond that have been motivated more by the ubiquity of file sharing than earnest effort. Still, go read Scott's impressive Wikipedia page and dig in a little further if his name rings no bells for you.
