Mascara-wearing, syringe-loving, 'School’s Out'-singing shock rocker Alice Cooper doesn’t do anything subtly or halfway. Then it's no surprise that the legendary performer hadn’t missed a concert in 30 years -- until last week.

Coop was forced to cancel a show last Thursday (May 26) due to food poisoning. He was reportedly feeling too sick and "zombieish" to leave the hotel in Santiago, Chile.

"I spoke with him a little bit ago, and he is feeling almost 100% better, though he is still pretty weak, which confirms that it was food poisoning and not some bug," Cooper’s assistant KC wrote on his official website.

"Naturally Alice hates to cancel shows," KC added. "As I went to bed last night, I thought about the fact that Alice hadn't canceled a show due to illness in 30 years. ... That's about as long as I've been alive! How many people can say they haven't taken a sick day in 30 years? Pretty impressive. ... Alice thanks everyone for their thoughts, prayers and kind words."

Cooper’s long-awaited upcoming album, ‘Welcome 2 My Nightmare,’ is set to drop next year, and the rocker has performed the new song 'I’ll Bite Your Face Off' during his current shows. The impending disc features an appearance by the original 'Nightmare' cast of Steve Hunter and Dick Wagner, while surviving Cooper members Michael Bruce, Dennis Dunaway and Neal Smith play on 'When Hell Comes Home.' Regarding surprises, country performer Vince Gill -- an unlikely comrade of Coop’s -- guests on a song called 'Runaway Train.'

Alice Cooper's overseas tour continues through a July 9 gig in Kvinesdal, Norway. A North American trek launches Aug. 5 in Billings, Mont.
