Bristol-based writer and artist Holly Corfield Carr made this brief but effective videopoem in 2014 as a promo for a live event called MINE, which she describes on Vimeo as

A poetic excavation of second-best diamonds

MINE journeys into the extraordinary underworld of an 18th-century grotto, a cave blistered with crystals and coral collected from slavers’ ports, to tell a story of dolour and dolerite amongst the city’s dealt dirt.

An audience of six descend with writer Holly Corfield Carr to play cards, trade voices and dig up a murder mystery, a disastrous meeting, a comedy, a spiralling inferno.

MINE was part of a 9-day arts festival held in September, 2014 for the Bristol Biennial. As for the videopoem, Carr writes:

To transfer some time back to you, I’ve piled it all up into a rushed sort of stalagmite. There’s about two million years here. So we’re even.
