More than four decades ago four high school kids from Dublin started a band that would become one of the biggest rock groups in the world. In 2019, U2 can still be listed alongside the likes of the Rolling Stones as one of the most influential legacy rock bands still touring. U2 just, like, won’t go away. Even now, they’re plotting another leg of their 30th-anniversary Joshua Tree tour — which started in 2017. They also spent a chunk of 2018 on the road for their latest album, Songs of Experience. In a lull between albums—presumably for Bono to get some sleep between music and saving the world—it's a good time to look back at U2's catalog and run down their best work.
