Perhaps you’ve never heard of Montaigne, an Australian art-pop artist who’s released a couple of albums and who represented her homeland at the Eurovision Song Contest last year. If that’s the case, don’t feel bad. David Byrne, elder god of art-pop, had never heard of Montaigne, either. But when Montaigne reached out for a collaboration, Byrne became a fan, and the two have now teamed up for a new single called “Always Be You.”
