During the course of his musical career, Neil Young has made a name for himself by doing whatever he pleases. He’s abandoned concert tours, released albums his labels found profoundly noncommercial, walked away from book deals and attacked fellow rockers for selling out to Madison Ave. This mercurial streak explains a lot about “Greendale” (8 p.m. today, Sundance), a 2004 film effort that serves as an extended video for an album of the same name.

Shot like a student movie in Super 8mm, complete with jerky camera movements and loosely synched mouths and music, “Greendale” is director Young’s attempt to create a visual novel, a musical meditation on small-town life.

¢ September marks the 100th birthday of director Michael Powell, one of the most original and visually audacious filmmakers of the 20th century. Turner Classic Movies salutes Powell with a monthlong Sunday-night showcase of his films, beginning with the Scottish drama “The Edge of the World” (7 p.m. Sunday, TCM) and the 1940 spectacle “The Thief of Baghdad” (8:45 p.m.), praised by Leonard Maltin for its “spectacular use of Technicolor.”
