In 1971, the New Orleans funk guitarist for The Meters made a James Taylor-style singer-songwriter album called Another Side.

It should look and taste great, with lighting by Klip Collective, wine and tomato pie by Joe Beddia, and vendors including Middle Child, Dizengoff, and Pitruco Pizza.

Yo La Tengo, Snail Mail, Rocket From the Crypt, Superchunk, Titus Andronicus, Shannon & the Clams, and Philly trio Control Top are down the shore at this 10 hour fest at Atlantic City’s Orange Loop Amphitheater.

This double bill of influential electronic 1980s British bands has been pushed back by the pandemic twice. But at long last, Neil Tennant and Chris Lowe of the witty, incisive Pet Shop Boys, and Bernard Sumner of synth-driven Joy Division successors New Order, are on the road on their Unity Tour. The two acts are alternating as headliners, and at the Mann, New Order will go on last.

It’s surprising how well it works; not terribly profound, perhaps, but deeply felt and empathetic. And don’t worry, they’ll play “Mr. Brightside.” Johnny Marr opens. $34.25-$124.25, 7:30 p.m., 9/27, Wells Fargo Center, 3601 S. Broad St., wellsfargocenterphilly.com

The singer, rapper, flautist, and positivity spreader comes to South Philly.
