1. Joe “King” Carrasco appears crowdsurfing in 1981 music video

In his video for "Party Weekend,” Carrasco can be seen surfing on a sea of hands. Although he didn’t invent the mosh pit as we know it (it’s hard to say who did), he is believed to be the first musician to crowdsurf in a music video.

At this famously messy show, audience members threw clumps of mud onstage, and they can be seen whizzing by Green Day singer Billie Joe Armstrong as he sings.

3. Warped Tour’s swimming pool mosh pit

5. Fan dies at Smashing Pumpkins’ set

Not all of mosh pit history is pretty. In 1996, a girl at a Smashing Pumpkins show in Dublin, Ireland, was killed after she suffered a heart attack from being pushed too hard in the pit. The band also took a stance against mosh pits following the casualty. This instance marked the first mosh pit-caused death.

6. Iggy Azalea’s twerk pit

Iggy Azalea may fall into the mainstream realm, but she’s been known to give a shout-out to the alt-world. At the beginning of the year, the singer came under fire for donning that Cradle Of Filth shirt, but it clearly didn’t deter her from her metal interest. As a result, she gave the mosh pit a revamp with the twerk pit. It all went down in July during the rapper’s two special, one-night only gigs in Los Angeles and New York City. There, she placed a yellow circle on the floor labeled “twerk pit” to encourage fans to let loose and even joined them herself to make it rain.

7. DevilDriver attempts to create a world record for the biggest circle pit

At their 2007 Download performance, metal band DevilDriver reportedly got 25,000 fans to create a circle pit in front of the stage. However, their record was rejected by Guinness World Records because it is impossible to definitively measure the size of a mosh pit, since it’s not clear where the moshing begins or ends.

8. The 68-foot stage dive by Boy Hits Car singer

10. Science of mosh pits discovered

In what might be the nerdiest discovery of mosh pit culture, Cornell scientists discovered that moshers behave like the molecules in a gas, moving and bumping into each other at high speeds. This research has helped with disaster planning, and also mosh pit preparation.

12. Fans mosh around a fire at a Bullet For My Valentine show

Is this something that you could call a fire pit? Not sure. But it created utter insanity (and huge amounts of danger) when Bullet For My Valentine fans started a bonfire at an indoor Russian show and started dancing around it.

13. Shaq

No one has ever had more fun in a mosh pit than Shaq. The athlete threw down during DJ Kill The Noise’s set at Tomorrowland in Belgium in July. This wasn’t the first or last time the EDM fan has hit the pit, returning to do the same at an Electric Zoo after party in August.

14. Chelsea Grin fan eats cereal during mosh
