Some longtime fans of Green Day have criticized the band for straying away from their rebellious punk roots. Those who think Green Day have gone soft better take a look at the following video, as the trio expressed their displeasure for having their set cut short at this weekend's iHeartRadio Festival.

Green Day were part of a diverse lineup during the first night of the two-day event at the MGM Grand in Las Vegas, Nevada. According to YouTube user xClandestinex, the band's performance time was shortened from 45 minutes to just 25 so that R&B superstar Usher could have a longer set. This didn't sit too well with frontman Billie Joe Armstrong, as you can see in the clip below.

Green Day were performing their 1994 hit, "Basket Case," when Armstrong decided to abruptly stop playing. The singer then stated he wanted to play a new song before telling the audience that they had only one minute left.

"Giving me a f---ing break. One minute left," Armstrong ranted while looking at the teleprompter that displayed "1 minute". "You're going to give me f---ing one minute? Let me f---ing tell you something. I've been around since f---ing 19-80-f---ing-8. And you're going to give me one f---ing minute? You gotta be f---ing kidding me!"

Armstrong wasn't finished, even referencing a certain Canadian teen pop star. "What the f--k," he continued. "I'm not f---ing Justin Bieber, you motherf---ers! You gotta be f---ing joking! I got one minute left. Oh, now I got nothing left. Let me show you what one f---ing minute f---ing means."

That's when Armstrong proceeded to smash his guitar on the stage. Bassist Mike Dirnt joined in on the fun and swung his instrument to the ground as well. Unfortunately drummer Tre Cool didn't roll around on his drum kit. The band walked off the stage after that.

Well, this will certainly bring attention that Green Day are releasing their new album, ¡Uno!, this Tuesday (September 25). It's part of a trilogy of albums that precedes ¡Dos! and ¡Tré!. Armstrong seemed to be in good health - at least for the most part - after having to be rushed to a hospital in Italy.

Do you think Green Day were in the right, or should they have shown more composure? Sound off below.
