Moses Sumney isn’t taking interviews right now. But his manager is happy to put this writer and a photographer on the list for Sumney’s Monday performance at the Sinclair. Her message - or maybe it’s Sumney’s - seems pretty clear. Meet the musician through his music. Questions can come later. (Another possibility is that the Harvard Advocate isn’t exactly the sort of media outlet that Sumney, fresh from collaborations with Solange and Beck, and recent mastermind behind the genre-defying soul/folk/synth/choral creation that is Aromanticism, is going to entertain. But you can decide for yourself.) Anyway, we go. They are, after all, free tickets to a Moses Sumney concert.Live, Sumney embodies the same certainty that an interview refusal kind of implies. He jokes with the crowd, he heckles, he splits the audience of mostly-college students to self select into a two-part harmony by asking us whether or not we were rejected by Harvard College.
