1) Snocore was conceived as a touring event to combat a slow time for live music and, even better, as an excuse for musicians to play mountain resort towns. The latter goal has waned in recent years, but the former still applies, and that’s all that matters if you have tickets to tonight’s show at Altar Bar. Flyleaf headlines this year’s Snocore. It has been a tumultuous couple years for the Texas quintet. Their lead singer quit in 2012 and their new singer, Kristen May, was saddened by the breakup of her previous band, Vedera. Flyleaf soldiered on, channelling this tumult into their newest album, 2014’s Between the Stars, to recreate their heavy metal sound. They are best known for the 2009 album Memento Mori, which hit number 8 on the Billboard 200. Adelitas Way, Framing Hanley, Fit For Rivals, Descendsion open. 7 p.m. 1620 Penn Ave., Strip District.
2) The music from one of the most beloved movies of all time—Casablanca—will be performed tonight by the Pittsburgh Symphony Orchestra. Max Steiner’s score for the 1942 film garnered an Oscar nomination. Relive the romantic war-time drama of star-crossed lovers Rick (Humphrey Bogart) and Ilsa (Ingrid Bergman) through the magical music. Tonight’s performance will be conducted by Emil de Cou. 8 p.m. Heinz Hall, 600 Penn Ave., Cultural District.
3) Mr. Joy is a solo show written by the New York-based playwright Daniel Beaty, who often draws his material from the everyday life of Harlem’s neighborhoods. The play centers on a shoe repair shop founded by a Chinese immigrant whose value to the community becomes evident one fateful day when customers arrive to find the shop closed. Actress Tangela Large plays all the parts, ranging from a budding young shoe designer to a “gangsta granny.” The show has been workshopped in New York and elsewhere, and Pittsburgh’s City Theatre is giving Mr. Joy its full-blown world premiere. 2 p.m. Closes today. 13th and Bingham streets, South Side.
