Normally, I wouldn't probably recommend watching an entire concert shot by a fan and posted on Youtube...except this video is really quite good....and it's U2!
During the Joshua Tree 2017 tour stop in Chicago last week at Soldier Field, YouTube user Paper Dolling Films captured video of the ENTIRE show, and it's quality.
Gives you a pretty good idea of what we can expect from the show at The Linc on Sunday here in Philly.
