Pentatonix A Capella at Stage AE (CP’s Mon. 7/22/13)

1) Pentatonix will belt out some musical medicine capable of curing even the most severe case of the Mondays tonight at Stage AE. This five-piece a cappella group combines undeniable vocal talent with a knack for beat-boxed rhythms and grooves, creating a sonic experience scarcely matched on any level. The group won season three of NBC’s “The Sing-Off,” and their debut extended-play, PTX Vol. 1, charted at No. 14 on the Billboard 200 Charts in the summer of 2012. Fun, energetic, and supremely talented—that’s Pentatonix. Gates open at 7 p.m. 400 North Shore Dr., North Shore.

2) Indie-rockers Northern Faces are set to electrify the Smiling Moose with their ambient, harmonious grooves and tunes. The Equal Vision Records standouts stroll into the Steel City off the recent release of their extended-play Southern Places, a debut that’s been met with positive reviews and significant buzz. The group’s smooth delivery and musical proficiency induces a happy spirit and brotherly vibes, so bring your dancing shoes and get ready to move. Opening act begins at 6:30 p.m. Upstairs. 1306 E. Carson St.

3) Take a break from your manic work schedule at Market Square, where noted musician Zig Daniels will perform as part of this week’s Mellow Mondays. Daniels, who was recently chosen as one of “Pittsburgh’s 50 Finest” by the Western PA Chapter of the Cystic Fibrosis Foundation, has played across the U.S. and Europe, pleasing audiences with his seemingly limitless set lists and well-rounded musical capabilities. Daniels is known to accept audience requests at his shows, so bring a list of your favorite tunes, and you might be treated to a special performance! Noon – 1 p.m. Free. 23 Market Place, Market Place, Downtown.

4) Go directly to jail—the Old Allegheny County Jail Museum, that is. A tour of this historic location, guided by a Pittsburgh History and Landmarks Foundation docent, is featured today, providing insight to the jail’s construction, purpose, and eventual renovation. Learn about this Pittsburgh treasure, and see why the location is so determinedly preserved. Note: Cameras are strictly prohibited. 11:30 a.m. – 1 p.m. Free. 440 Ross St., Downtown

5) Liven your child’s summer vacation through recyclable artmaking courtesy of Pittsburgh-based art instructor and educator Alison K. Babusci at ArtCity: Green Artists. The weeklong event, which is open to children ages 8 – 10, aims to inspire and instruct through hands-on activities and stimulating collaboration, using yesterday’s trash to craft the masterpieces of tomorrow. Hosted at the Trust Arts Education Center, this production expertly blends education with activity, a combination guaranteed to thrill the youngsters. 10 a.m. – 2 p.m., Monday – Friday. $95 for the first registrant, $75 for additional siblings. 805-807 Liberty Ave. Cultural District.
