Only on the "CBS This Morning" podcast, co-host Tony Dokoupil talks with Jamie Schutz, the producer of a new documentary about the creative process of Phish lead singer Trey Anastasio. Schutz says "Between Me and My Mind" portrays Anastasio as a workaholic who's constantly thinking about his music and shows the band's growth from its first loyal fan base in Burlington, Vermont to nationwide success. Schutz discusses Anastasio's struggle with sobriety and how his early life impacted his creative process. Plus, Dokoupil gains a better understanding of his wife, Phish Phan and MSNBC anchor Katy Tur.
