Jim Jarmusch's low-tech tribute to the 30-year-old collaboration between grunge godfather Neil Young and his favorite garage band, Crazy Horse, is both a quirky little movie and a monument to one of rock & roll's greatest noisemakers. Partially culled from some gritty archival material shot in 1976 and 1986, and supplemented by lots of super-8 footage of Young and Crazy Horse between shows while on a concert tour (the concert footage itself appears to be shot on 16mm), Year of the Horse is very much like one of the band's paradoxical performances: epic but transitory, ragged but direct, focused but improvisational. Jarmusch understands Crazy Horse and its quixotic musical quest too well to embalm them in a conventional profile-and-performance "rockumentary." Instead, he honors the off-and-on marriage of Young and the others by treating the various chapters of their lives together as shadows in time, fleeting glimpses of a brotherhood that has no secrets.
