An excellent film about the use of the turntable as instrument (not in the hip hop scratching sense) and especially fascinating to see as I’m currently developing something along the same lines for performance. Go here for the original article on the Vinyl Factory site and try to see Graham Dunning live if you can, what he does is incredible.
Also just premiered via Resident Advisor is a film about dubplate cutting and present in both films is Shiva Fesharecki who performs both in clubs and concert halls with turntables.
