Girls & Boys: Porter Robinson + Madeon

Alex English and GBH are back with their big electronic-dance-music bash, the Girls & Boys affair, held in Webster Hall’s massive Grand Ballroom. Porter Robinson is something of an electronic-music wunderkind (as borne out by the fact that he's headlining Webster Hall at age 19); he's celebrating the release of his new Spitfire EP on the Skrillex-run OWSLA label. The French electropop producer Madeon, meanwhile, is 17 years old—what the hell are they feeding kids these days?
