It's my (and many others') pick for the best rock concert movie ever: Martin Scorsese's The Last Waltz. For those in the dark, this was Scorsese's filming of The Band's farewell concert at San Francisco's Winterland Ballroom on Thanksgiving Day, 1976.
Jimmy Carbone of Jimmy's No. 43 hosted the "Battle of the Belgians" at his cozy, subterranean East Village bar. This festive event pitted Belgian-style American beers against their authentic counterparts.
More than any other director I can think of, Scorsese is totally, 100% committed to the art of cinema, the classic example of someone doing what he's best at and what he loves. This is a man gloriously consumed by film.
