Instrument: Ten Years with the Band Fugazi

This feature length 'measurement' (the title plays with the idea of musicians taking measure of their world) of the US alt-rock band Fugazi ('a messed-up situation') collates material of the band at work and play, on the road and on public access TV, with portraits of and interviews with their fans and other concertgoers. Its core, however, is built around promo- and film-maker Jem Cohen's own accumulation of film and video footage spanning a decade. The documentary emphasises what makes the band special both onstage (its angular, distended, semi-improvised brand of agit-rock and freeform performance) and off (a dedication to affordable popular access, commercial independence and political activism), but not, significantly, on record - and the songs themselves not being immediately endearing to the uninitiated, the incorporation of 20-odd numbers over two hours can certainly wear.
