Blank Generation on Google Video

This excellent punk documentary can be seen in its entirety right here. It covers both the New York scene (Ramones, Television, Patti Smith) and London (Sex Pistols, Clash, Damned, Buzzcocks) comprehensively. It's very well made, and limits its hour-long time to the most nascent years of the music, ending around the time the Pistols broke up in '78.
