Enjoy an evening of contemporary acoustic music, soaring vocal harmonies, and a percussive tribal/world-beat vibe performed on an unusual mix of ancient and modern instruments, all focused on the theme of Spring Equinox (beginning of Spring) as a time of re-birth and renewed energy. Some of this concert will be performed in total darkness, illuminated by periods of flickering candlelight, providing a visually rich, spell-binding setting and mesmerizing listening environment.

Featuring Rudi Harst  (songwriter, vocals, guitar, Native American flute, Tibetan bowls), Steve Daniel (didgeridoo), Ray Palmer (keyboard), Kevin Lewis (bass), Kiko Guerrero (percussion), Mary Moseley (handpan drum), Sarah Gabriel (vocals), and Olivia de Jesus (vocals/guitar).

This marks the 21st year that Rudi and his musical friends have been celebrating the changing of seasons with this series of remarkable concerts, Underground Sounds, performed in the stunningly beautiful Cave Throne Room.
