PODCAST: Cellist and composer Zoe Keating discusses her song, “Optimist.”

Keating uses a cello and a foot-controlled laptop to record layers of cello, creating intricate music. She is known for her use of technology – which she uses to sample her cello onstage – and for her DIY approach: she releases her music online without the help of a record label and has been open and critical of the music industry and the royalties artists receive.
