Was trouble at the Rolling Stones' disastrous Altamont concert predicted by tarot cards?

Did a tarot card reading predict the Rolling Stones’ Altamont disaster 50 years ago? On Dec. 6, 1969 — “perhaps rock and roll’s all-time worst day ... a day when everything went perfectly wrong,” according to Rolling Stone magazine — one of the greatest tragedies in music history occurred, at the Rolling Stones’ free festival at Northern California’s Altamont Speedway.
