As a producer, writer, recording artist and entrepreneur, Poo Bear is always searching for collaborators who bring out the best in him, and vice versa. "Do you believe in me?," he'll ask an artist who wants to record one of his songs, because for him, the best work arises when there is that mutual passion for each other's work. He's definitely found that zone with Justin Bieber, his most extensive song partner over the past several years. But his prolific work includes hundreds of tunes, for artists as varied as Jill Scott, the Zac Brown Band, J. Balvin and FKA Twigs, to name just a few. In this conversation, we talk about his earliest projects (as a kid, singing in R&B groups in Atlanta, and writing professionally from the time he was 16), how he has evolved his songwriting formula, where he sees pop music going in the future, and more.
