Kanye West performs in a mask on the main stage at Wireless festival in Finsbury Park, north London, Friday, July 4, 2014.

Kanye West, known for his long-winded rants, is at it again.

This time, West interrupted his closing set at the Wireless Festival on July 4 th with more of a rant then a rap to a crowd that quickly turned from applause to boos.

Concert goers said West free-style ranted for more than 20 minutes on a range of topics from discrimination within the fashion industry to his marriage to Kim Kardashian. And in true Kanye style, he donned a glittery, bejeweled full-faced mask during his performance at Finsbury Park in London.

West, 37, paused his headlining act when he began to preach to the crowd after finishing "Runaway" about his talents and all of the crowd's talents and creative potential, too.

West also told the crowd to follow their dreams because he told his wife, Kim Kardashian, seven years ago that he was going to marry her and didn't say "try."

It's not the first time West has engaged in an on-stage venting session, however, his speech Friday night had some notable moments.

"You know, people be looking at me like I got a problem or something," West began his auto-tuned lecture. "Like I'm uncontrollable, or something."

But as far as he is concerned, everyone is a star, West sang to kick off his off-the-cuff remarks.

West made sure to let the crowd know his thoughts on the media's representation of his image.

"First thing they do is crush your dreams, then add a couple drops of low self-esteem," West said. "And control you with lies, control you with lies, control you lies, but we going out of control tonight."

West went on to say he has been the victim of "dishumanization" from his critics, admitting he just invented the word on the spot.

"What have I ever done that was so wrong, other than believing in myself? If believing in yourself is so so so wrong, and the other side is so so so so strong in trying to beat down, and demonize and dishumanize and I don't know if that's a word or not, and if it's not a word then I said it's a (beeping) word."

West said he's not particularly angry, but the media spins the idea of celebrity to make West seem stupid, he explained.

"I'm not going to call no names, I'm not going to say Nike or anything," West added.

"I'm not dissing Louis Vuitton, I'm not dissing the Gucci group," West said. "I'm just saying don't discriminate against me because I'm a black man or because I'm a celebrity to determine that I can't create."

West is known for his bold statements and long speeches.

"I am the No. 1 most impactful artist of our generation," he told Sway Calloway in a SiriusXM interview last year on "Sway in the Morning." "I am Shakespeare in the flesh. Walt Disney. Nike. Google… Do you want to marginalize me until I am out my moment?"

And during his recent wedding, Kanye gave a 20-minute speech and declared the Kardashian family "the most remarkable people of our time" who can "make the world a better place."

West's rant last night was met with boos and jeers.

"After about 10 minutes, the boos started and I saw a lot of people leaving," concert goer Amie Holdsworth said. "He also had a go at the camera guy and told them to turn off the side screens a few times."

"They were also shouting and swearing at him to get on with it," audience member Gemma Gould said.

West is also scheduled to headline the second night tonight, due to Drake's recent cancellation, as well as closing the show on Sunday.
