It’s been a while since a traveling ‘festival’ made waves. Warped Tour was a cultural monolith that is still remembered fondly today. AEG might be angling to fill that void with Re:SET, a nationwide touring concert series. Here’s how it works: throughout each weekend in June, AEG chose three geographically close metro areas to host three sets of artists on Friday, Saturday, and Sunday. Merriweather Post Pavilion hosted indie rock supergroup Boygenius on Friday (along with Clairo, Dijon, and Bartees Strange), R&B wunderkind Steve Lacy on Saturday (with James Blake, Toro Y Moi, and Fousheé), and the long-influential LCD Soundsystem on Sunday (with Jamie xx, IDLES, and L’Rain). Boston and New York City also had simultaneous Re:SET events all weekend, trading bands between the three cities.
