On Bells Larsen’s stunning new album, “Blurring Time,” the Canadian singer-songwriter has an unlikely collaborator — himself. Bells is a trans man and he first recorded the album in his pre-transition voice with the intent of revisiting the songs after he started hormone therapy. The result is a unique self-collaboration, in which he harmonizes with himself. Bells sits down with Tom Power to talk about the new album and having to cancel his U.S. tour. If you like this conversation, take a listen to Tom’s chat with singer-songwriter T. Thomason.
