1) Enjoy the thought-provoking lyrics and classic riffs of folk singer/songwriter Peter Mulvey at Club Café. Accompanied by his band, Crumbling Beauties, Mulvey entices audiences all over the world with his combination of rock and soul along with his haunting voice. Mulvey incorporates storytelling into his tunes, like “Vlad the Astrophysicist,” then seamlessly segues into more upbeat tempos like those in “If Love is Not Enough.” In addition to his own songs, this seasoned artist may play some covers of songs you forgot how much you loved. With special guest The Damaged Pies. 8 p.m. 56-58 S. 12th St., South Side.
2) Join the self-proclaimed “cheesy ‘80s cover band” Velveeta at Jergel’s for a fun afternoon and evening of food, drinks, and some great tunes from the decade you hate to love. The event is a fundraiser, with all proceeds going to Penn State’s THON, the school’s annual drive to raise money and awareness to fight pediatric cancer. Whether you come to dance, eat, drink, or want to relive those days of big hair and Aquanet with your favorite ’80s songs (or, preferably, all of the above), you can proudly say that you’re supporting a great cause. Donations accepted at the door. 1- 8 p.m. 103 Slade Ln., Warrendale.
3) Moondog’s owner Ron Esser doesn’t typically open his Blawnox blues bar on Sundays, so when he does, we know it’s going to be for an impressive act. This Sunday, legendary blues and rock guitarist Tommy Castro performs with his band, The Painkillers, in a CD release party for their new album The Devil You Know. Castro’s vast guitar experience and his sultry voice, backed by his perfectly rhythmic band, combine to present a marriage of blues and rock in its most raw form. They make it look easy, and they make it look fun, as demonstrated in songs like “Greedy” and “Can’t Keep a Good Man Down.” Get there early to find the best seat in the house. 7:30 p.m. 378 Freeport Rd., Blawnox.
4) Take a trip back to the days of wacky antics and knee-slapping comedy with the Marx Brothers at Regent Square Theater’s showing of A Night at the Opera. Part of the Sunday Night Series “Laugh – It’ll Warm You Up!”, the 1935 classic features Groucho, Chico, and Harpo in a send-up of the highbrows of the time. What do you do when your chorus-bound friend is in love with the opera’s leading lady? If you’re the Marx Brothers, you can only do one thing: sabotage the opera, with as many laughs as possible along the way. 8 p.m. 1035 S. Braddock Ave., Regent Square.
