Here are some highlights from the fourth day:AdélaRising pop singer Adéla had a full-circle moment, drawing a substantial Sunday afternoon crowd to the T-Mobile Stage just like last year’s breakout stars Katseye. YOASOBIJapanese duo YOASOBI were amplified by their rocking live band with crunching guitar riffs (“Kaibutsu”) and sturdy basslines (“Undead,” “Yuusha”). Hot MulliganHot Mulligan brought pop-punk energy to Lollapalooza with their punchy guitar riffs and irreverent sense of humor/banter. The band brought their set to a strong finish with the driving guitar riffs of their anthemic “*Equip Sunglasses*.” Presented live, some heavier guitar sounds gave tracks like “Cut My Hair” and “Greedy” a darker edge.
