At the 2012 iHeartRadio Music Festival, Green Day front-man Billie Joe Armstrong launched into a rant when he realized that his band's set was almost over.
The video of the melt-down is above and the full performance is below. The language is NSFW.
Shortly after the rant, Armstrong checked into rehab.
The 2014 iHeartRadio Music Festival lineup was announced on Wednesday. Green Day was not on the bill.
