Speaking to Stereogum
about U2's relationship with Kendrick Lamar, The Edge said: "It was really just that we were fans. We were just thinking about artists we really respect and like, and he was on the top of our list. We look for artists that we feel have a similar spirit."
"There's a righteous anger that is hard to argue with," Bono added. "I asked him would he rap about where America is at, his reply was to rap about where America isn't at. Smart dude."
