Outside, a thunderstorm blasted. Inside, crowds of students had their own blast, as a lineup of hip-hop artists took the Fall Fest concert stage. The UB Student Association event drew thousands to Alumni Arena on Sept. 10 for performances by Rae Sremmurd, Lil Yachty, D.R.A.M. and headliner Travis Scott. Hands (and cameras) were in the air the whole night, prompting the Student Association to issue a post-show tip to concertgoers via Facebook: If you threw your phone onstage, you can pick it up in the Student Union on Monday.
