Chthonic Live: Ancient Females in the Red Rift of Rays - the fourth Chthonic Live channelling by artist Sophie Sleigh-Johnson, an invocation of ancient and ruptured temporalities, making crop circles on air. Embodiment meets exposition in live discussion with artist Maggie Roberts aka MER (Orphan Drift); divine females and spell archaeology with hierophant and arch-druidess Caroline Wise; and Templar architecture from Helen Gibson. All will be an impossible invocation; a moment constantly slipping away as permeable thresholds on air becomes alchemy inscribed in the walls. The voices are rising. Ghosts will be live. Let’s think out loud. [Repeated Monday 9am.]
