Good case of this is with Bruce Springsteen who is one of the best songwriter/performers this nation has ever produced. And I think you needed to have been to one of his four-hour concerts in the 1970s and 80s to really understand that. Unfortunately he started polluting his concert performances with political statements in between songs (Bono from U2 did that also) and I never had a desire to buy a Springsteen concert ticket again.
However, if not for the politics, I think Springsteen would be a favorite here on FR because his songs speak to Americana and the quality of his songwriting and performances are unassailable.
Why does Adele even care, she lives in high tax England. Do US politics really interest her at all.
By the way she has a complete sold out USA tour coming up very soon. It’s all PR and she is getting new fans and exposure.
