Not just a Magyar version of This Is Spinal Tap but a powerful expression of working-class frustration, this raunchy (pseudo) rockumentary unfolds against a bleak, beer-sodden world of geeky villages and dreary suburbs. Colorado, a shaggy bunch of decrepit hippies who have been playing together for a decade and never managed even a single radio gig, make a last bid for the big time. Recruiting a one-legged Gypsy bluesman and renaming themselves Bald-Dog, they switch from pseudo American pop to a more authentically Hungarian "prole-rock." In addition to featuring credible music-performed by the Hobo Blues Band, Hungary's onetime answer to the Rolling Stones, and the irrepressible Gyula "Bill" Deák-Bald-Dog Rock shows scenes ranging from a rural hop at which teenagers twist to a toneless polka ensemble, to a pretentious official band performing amid a cloud of dry-ice vapors, to the rowdy, nihilistic crowds which Bald-Dog attracts until, with loutish integrity, the band self-destructs. Bald-Dog Rock appeared the same year as Hungary's first filmed rock concert, around the time a native punk movement burst upon the scene. The film is interspersed with quotes from Muddy Waters, Bob Dylan, and the Beatles-helpfully rendered in English, Russian, and Hungarian. J. Hoberman
