8. Crooners are king.
Two of the most popular performances on Saturday of Lollapalooza came from young men whose voices you really just have to hear to believe. After the gates opened back up after the storm on Saturday, thousands of fans rushed through the mud to the southern main stage to watch The Weeknd—22-year-old Abel Tesfaye—whose opening song "High For This" launched an epic singalong. Later, on a much smaller stage, Frank Ocean closed out the evening with a captivating, intimate set that included songs from his much-hyped new album Channel Orange. We dare you to listen to either one of these guys without getting the chills.
