‘HEAVY METAL'9 p.m., Downtown Music. $3.
For a certain set of folks who grew up in the '80s, this was the film to watch on psychedelics with a crew of buddies when someone's folks were out of town for the weekend. For the uninitiated, here's the gist: five short stories served with generous portions of animated graphic violence, nudity, sexuality and comedy and anchored by one of the greatest soundtracks ever recorded. The voice cast includes John Candy, Harold Ramis and Eugene Levy, and the soundtrack features Sammy Hagar, Cheap Trick, Black Sabbath, Nazareth and Devo. If you've never seen animated alien co-pilots (Candy and Ramis) whiff a space-sized rail of galactic cocaine (“Man, that's some great Nyborg”) and then argue over who gets to drive, (“Man, if it's one thing I know how to do, it's drive when I'm stoned”), now's your chance. There'll be 50-cent drafts, $2 well drinks, $3.50 pitchers and half-price food specials at Downtown Music on Sunday, too.
