One of the most buzzed-about rockumentaries of the past year and one of the best concert movies of all time will be screened in the Twin Cities over the next two nights.

Tonight at the Amsterdam Bar & Hall in downtown St. Paul, 89.3 the Current is hosting a free screening of "Big Easy Express," featuring Mumford & Sons, Edward Sharpe & the Magnetic Zeros and Old Crow Medicine Show on a train trek to New Orleans. Directed by Emmett Malloy, the film resembles Malloy's masterful White Stripes movie "Under Great White Northern Lights" with its travelogue approach and performances in unusual locations, such as a shipping yard. The screening starts at 7:30 p.m., but space is limited. So get there by 7.

On Thursday, the Parkway Theater in south Minneapolis will bring back AC/DC's classic film "Let There Be Rock" as part of Rob Chapman's "Rock 'n' Roll Picture Show" series. Cities 97 jockey Brian Oake and ex-Viking Mike Morris will help introduce the movie, which captures a single performance in Paris circa 1979 – just two months before Bon Scott's death. Tickets ($12) can be bought online or at the theater. Showtime is 7 p.m.
