The first in a series, this episode premieres a musical film about a mysterious and transformative encounter, showcases an in-studio performance by vocalist and composer Holland Andrews, and features a conversation between Holland and Joseph. 

Featuring new works, exclusive performances, and intimate conversations about life and art, this new music and variety program embraces the idea that with moments of uncertainty comes a weird invitation to dream. The program’s name is inspired by Cave of Harmony, Elsa Lanchester’s 1920s London nightclub.
