Connor Barwin’s benefit concert will return this summer with Alex G and Alvvays

Connor Barwin’s “Make The World Better” benefit is coming back in August with an indie rock double bill at the Dell Music Center.

The concert will feature two bright stars in the indie rock firmament — Philly songwriting savant Alex G and Toronto band Alvvays. All proceeds from the concert (after the bands get paid) will go to the former Philadelphia Eagles all-pro defensive end’s foundation, which rebuilds parks and rec centers in Philadelphia.

The Aug. 26 show is part of a seven-show summer tour that kicks off in Brooklyn.

The prolific Alex G — who was raised in Havertown and whose last name is Giannascoli — released his ninth and most richly rewarding album, God Save All the Animals, last year. He also composed the soundtrack to the horror movie We’re All Going to the World’s Fair.

Alvvays (pronounced “always) is a five-person band fronted by singer-guitarist Molly Rankin. The group’s third album, Blue Rev, is full of songs written by Rankin and Alec O’Hanley that are super-catchy, as are all Alvvays songs, and with growing narrative sophistication. Like God Save All the Animals, Blue Rev landed near the top of many year-end best-of lists.

This year’s benefit for MTWB, which Barwin founded with his mother, Margaret Bailey, in 2013, will be staged at the open-air Dell, a city-owned venue, for the fourth time.

Last year’s show, which marked a return after a two-year absence, was the most successful yet, with a headlining set by Japanese Breakfast, Yo La Tengo, and Kate Le Bon. It raised $250,000 f toward the rebuilding of the Vare Recreation Center in Grays Ferry.

Barwin, an avid music fan often seen at shows around town, is now the Eagles’ head of player development. He was the executive producer of A Philly Special Christmas, the album featuring Eagles linemen Jason Kelce, Jordan Mailata, and Lane Johnson that raised $1.25 million for Philly charities.

Tickets are $45 to $75 and are on sale through Union Transfer’s website, utphilly.com. A pre-sale began Wednesday, March 1, and tickets to the general public go on sale 10 a.m. Friday.
