Sonic Sanctuary in the woods · Kings Langley, Hertfordshire

The evening opens with ceremonial cacao. Then you lie down. For 90 minutes Tibetan singing bowls, gongs, and electronic frequencies move through a 1970s hi-fi system and into the body. The trees do the rest.

No experience needed. The frequency does the work.

Bring: a blanket, a warm layer, something to lie on.

Limited to 20.

Sonic Sanctuary is the practice of Kristy Harper; music producer and sound therapist working with Tibetan singing bowls, hi-fidelity electronics, and ancient instruments.

Note: ceremonial cacao is not suitable if you are pregnant, on SSRIs or MAOIs, or have a heart condition.
