This weekend’s forecast isn’t spectacular, but that won’t stop the many street festivals and markets from rolling out, including the opening of Spruce Street Harbor Park and Blue Cross RiverRink Summerfest.

Nor will it stop Mother’s Day. Plan ahead: Grace Dickinson offers 10 suggestions for spending time with mom that aren’t brunch. And if you need to buy a gift, consider an affordable go-to — a candle. Cassie Owens and Brandon Harden have a comprehensive guide to buying candles, from boutiques to botánicas, in Philly.

Also starting this Friday is PAFA’s Student Exhibition, which is a proving ground for young artists that often go on to international renown. It’s a prime chance to score fine art on the cheap — but it’s far from the only one. Tomorrow, look out for our guide to buying art on a budget in Philadelphia, complete with negotiating tips, annual art sales, and collectors’ best-kept secret.

MUSIC

Hunter Hayes

It’s been seven years since then 20-year-old Hunter Hayes had his chart-topping country hit with the rowdy but respectfully romantic ballad “Wanted.” Along with a handful of similar-sounding, shaggy puppy-loving smashes, “Wanted” defined the thoughtful young songwriter for better (cash) and worse (being stuck in a rut). That’s probably why a less lovesick and more ruminative 27-year-old Hayes’ wrote his forthcoming new album (untitled as yet) and is presenting the fresh songs of his Closer to You tour at the top of his live set. The baritone-voiced multi-instrumentalist once dubbed by Billboard as the Leader of Country Music’s Youth Revolution has grown up and wants his fans to know that up-front. — A.D. Amorosi

7:30 p.m., Friday, the Fillmore, 23 E. Allen St., $30, 215-309-0150, thefillmorephilly.com

Strand of Oaks

Tim Showalter of Philadelphia’s Strand of Oaks recorded his new album, Eraserland, in Louisville, Ky., last fall with a bunch of backing musicians. They included the members of My Morning Jacket (sans Jim James), Jason Isbell chipping in on guitar, and Emma Ruth Rundle on vocals. The songs put Showalter’s ideas about music’s ability to mend broken hearts and damaged psyches to the test, which Eraserland passes with flying colors. — Dan DeLuca

8 p.m., Friday, Union Transfer, 1026 Spring Garden St., $18, 215-232-2100, utphilly.com

Meat Puppets

Meat Puppets started out as a punk-rock band way back in 1980, and the Kirkwood brothers-led group soon thereafter transformed into the psychedelic-folk band that gained fame when appearing with Nirvana on MTV Unplugged in New York a few months before Kurt Cobain’s death in 1994. The Puppets are in fine form on their new sun-blistered 12th album, Dusty Notes, released on Megaforce Records in March. — D.D.

8 p.m., Friday, Underground Arts, 1200 Callowhill St., $20-$22, 215-627-1332, undergroundarts.org

Del McCoury & David Grisman

Del McCoury and David Grisman have been pals since the early ’60s, when McCoury was playing in Bill Monroe’s band and mandolinist Grisman was part of the NYC folk revival. That was before Grisman got the nickname “Dawg” from his friend and frequent collaborator Jerry Garcia, and before McCoury became a bluegrass star himself as a singer and guitarist. Eighty-year-old McCoury tours with his band — his sons — less frequently than he used to, but Del and Dawg, who’s 74, come to Wilmington’s Grand Opera House on Friday to sing old songs and tell stories together. They’re living legends. — Steve Klinge

8 p.m., Friday, the Grand Opera House, 818 N. Market St., Wilmington, $35 to $42, 302-652-5577, thegrandwilmington.org

Balance & Composure

When it comes to making dramatic, dynamic post-hardcore with more smarts than emotion and a fast-slow Nirvana-like boiling point, Doylestown’s Balance & Composure has it all sewn up. B&C albums such as The Things We Think We’re Missing (2013) and Light We Made (2016) rage passionately, with a complexity worth their weight in prog gold. So, what’s all this about them having announced a farewell tour, with these shows being perhaps the last we’ll see of B&C? Remember, these guys love their drama. Stay tuned. — A.D.A.

Michael Martin Murphey

It’s a rare visit to these parts for Michael Martin Murphey, but the 74-year-old singer-songwriter remains as active as ever. His latest album, Austinology: Alleys of Austin, is a reminder of the key role the Dallas native played with such peers as Willie Nelson and Jerry Jeff Walker in creating the progressive country-rock-folk hybrid that made the Texas capital such an influential music scene in the early ’70s. As Murphey offers new takes on some of his best-known songs (“Wildfire,” “Geronimo’s Cadillac”) as well as numbers by contemporaries like Townes Van Zandt and Guy Clark, he’s joined on the album not only by Nelson and Walker, but by younger Lone Star singer-songwriters they have influenced, including Lyle Lovett, Steve Earle, Bruce Robison, and Randy Rogers. — Nick Cristiano
