Joe Elliott Gets Altitude Sickness, Powers Through Performance

Joe Elliott showed this past weekend what a pro he is by overcoming altitude sickness while on tour in Bogota, Colombia.

The Def Leppard frontman had to briefly seek treatment at a local hospital for altitude sickness the night before the band's February 25 show. (A simple Google search of "Bogota Columbia altitude" will yield many results for how to avoid altitude sickness. After all, the city is a whopping 8,660 ft above sea level.)

In a video shared to Def Leppard's social media channels, Elliott said, in part, "5:20 PM. We're on at 8, so I am alive and well. Little woozy, I'll be honest. Moderate to severe altitude sickness. I would hate to know what 'severe' altitude sickness [is.] I wouldn't want to wish that on my worst enemy."

He added, "But here I am. I wanted to put everyone at rest, because apparently, the internet lit up. So, I'm here to put everyone that cares about it, their minds at rest."

In a fan-shot video, Elliott addressed the crowd saying, "Before we carry on, I'd just like to say a big thanks to all the staff at the Marly hospital who took care of me last night. I was feeling a little bit under the weather. We call it altitude sickness – you have another word for it that we can’t pronounce. I made it, you made it, and thanks to them, that’s why I’m here. So let’s make some noise for all those good folks at the Marly hospital please."

Def Leppard is currently on tour with Motley Crue in South America. That leg of the tour will end on March 9 in Buenos Aires, Argentina. The co-headlining tour will then perform a one-off show at the Seminole Hard Rock Hotel & Casino in Hollywood, Fla. on March 12. After a break from the road, their tour heads overseas for a European tour beginning on May 22. A full list of upcoming dates can be found at DefLeppard.com.

A number of bands have one diamond-certified title, and even fewer have more than one. However, there is an elite group of rock bands with multiple diamond-certified studio albums.

The Recording Industry Association of America (RIAA) has given out a number of diamond certifications to various albums that have sold at least 10 million units. Several of those albums happen to be greatest hits/best-of compilations. Thanks to these releases, this has led to a variety of bands have more than one diamond-certified title.

Believe it or not, there are only five rock bands to have more than one diamond-certified studio albums. That's right, only five.

So, who are they? Scroll through the gallery below to find out and to see which of their studio albums have moved 10 million units or more.
