In this episode of the Music Biz Podcast, we talk with D.A. Wallach, who is a musician, Spotify’s first artist-in-residence, and an adviser for several other technology companies. D.A. put out an essay last year titled "Bitcoin for Rockstars: How Cryptocurrency Can Help Revolutionize The Music Industry," which discusses how blockchain technologies can help the music industry at large with tracking metadata, and moving payments. We talk to D.A. about his essay, his views on blockchain, and how he manages a career in music while also investing in technology companies.
