Despite the music portion of the festival not beginning until Friday, one person has reportedly died at Glastonbury Festival in the U.K. According to the Mirror, a 67-year old woman passed away today from what police suspect to be natural causes. They are not treating the situation as suspicious.

In addition, a 26-year old man is in “life-threatening condition” after overdosing on ketamine. Police have also already made 12 arrests for drug-related arrests on the eve of the opening day of the festival.

Glastonbury will feature performances from the likes of Arcade Fire, Metallica, Skrillex, Jack White, Elbow, The Black Keys and many, many more.
