In this 2004 video documentary S.A. Crary struggles to explain the eruption and influence of the extreme rock underground that began with the late-70s “no wave” scene and eventually generated acts like Swans and Sonic Youth. The music's desperation and intensity are powerfully conveyed in grainy performance footage of DNA, the Theoretical Girls, and Teenage Jesus & the Jerks, though aside from a scalding nihilism, its ethos remains obscure. Crary surveys the younger generation of New York art-rockers (Liars, Black Dice, the Yeah Yeah Yeahs), who draw inspiration from the earlier groups but lack their hunger, depth, and vision. Among the talking heads are Thurston Moore, Michael Gira, Martin Rev, Arto Lindsay, Lydia Lunch, and Glenn Branca. 75 min.
