This year's Glastonbury Festival hasn't really even brought out the big acts yet, and there have already been two deaths. A 67-year-old woman died of natural causes yesterday, and now a 26-year-old man who was reported in critical condition has passed away.

According to NME, the man overdosed after taking the drug ketamine. He was reported in "life-threatening condition" yesterday after taking the drug the night before. Glastonbury Police issued the news on its Twitter this morning:

A spokesman for local police told NME that the drug was contaminated and that they're considering this incident an "individual reaction." "This is another tragic reminder of the risks of experimenting with drugs," the spokesman said.

It's been a pretty lousy week for live-music fans so far. Two people died last weekend at the Electric Daisy Carnival in Las Vegas. And on Wednesday night, 36 people were rushed to the hospital at a Boston concert by EDM DJ Avicii.
