Paul McCartney, Metallica, and Florence And The Machine will headline this year’s very hip, very now Lollapalooza festival, held July 31 to August 2 in Chicago. Sam Smith, Bassnectar, and The Weeknd join the fest as second stage headliners, while acts like Alt-J, Alabama Shakes, Of Monsters And Men, Tame Impala, A$AP Rocky, Kid Cudi, Brand New, TV On The Radio, Cary Clark Jr., and Kaskade round out the fest’s semi-big names. It’s worth noting that this year’s line-up is slightly more underwhelming than other recent rosters, something that could be a symptom of both the glut of festivals in the marketplace or the lack of true headliner-sized acts in music right now.
