I saw them at Rice Eccles (the tour with the claw thing that now sits by the freeway)
And I enjoyed Bono and Edge's fairly recent Tiny Desk Concert that featured a few stripped down acoustic versions of their songs
And if I could time travel to see a show live, I would strongly consider the tour featured in the Rattle and Hum movie
It's just strange to me that I have most of their albums on my phone, and I almost never choose to listen to them
