SUMMER SCREEN: Great Scott! "Back to the Future" will be playing tonight as a part of the NoMa Summer Screen outdoor film series (L Street between 2nd and 3rd streets N.E.).

KARAOKE NIGHT: Grab a costume and shun your fear of humiliation when Solly's Tavern (1942 11th St. N.W.) holds its bimonthly Kostume Karaoke. Break out the wigs, capes and makeup, and figure out which terrifying '80s song to call your very own. 8 p.m.; no cover.
