Suggesting that the annual music festival will now have even more opportunities to be rained out, next year’s Lollapalooza will extend to four days instead of three. That comes from The Chicago Tribune, which reports that this extra day has been added in honor of Lollapalooza’s 25th anniversary and it will allow the organizers to book 170 bands. Also, Lollapalooza reportedly hasn’t cleared this extra day with Chicago for any years beyond 2016, so this four-day thing might only happen once. Seeing as how the tickets always sell out in an instant, though, the fact that this will certainly make a shitload of money will probably grease some of the city’s famously greaseable wheels.
