Rufus Wainwright is a difficult artist to categorize at the best of times. As a musician, he’s recorded pop songs, folk music, operas and stage musicals. But his new album, “Dream Requiem,” is a little different, even for him. It’s a religious work inspired by a range of subjects, including a poem by Lord Byron, the music of Giuseppe Verdi, and his beloved late dog Puccini. He also managed to recruit Meryl Streep to narrate the project. Rufus joins Tom Power over Zoom to talk about the different influences behind “Dream Requiem,” his upbringing in Quebec, and how this project really mourns the death of the American Dream.
