Kanye West failed to entertain his fans during the Wireless Festival in London on Friday night. The rapper was booed by the crowd after he launched into a mid-performance 20-minute rant.

The rapper paused his performance at the London music fest held at Finsbury Park, to preach to the crowd about discrimination within the fashion industry, reports Daily Mail.

West wore a bejewelled mask over his face while telling the audience: 'I'm not going to mention any names but... Nike, Louis Vuitton and Gucci. Don't discriminate against me 'cos I'm a black man making music.

One festival-goer told MailOnline: 'He was laying into the "machine" and ranting about the public's perception of him. Hundreds of people left the park early because they were so bored of his long rant.'

Kanye took to the stage with performances of 'Mercy', 'All Of The Lights', 'Touch The Sky', 'Blood On The Leaves'; and other songs, but not before taking a 20-minute break in the middle of his set to get a few things off his chest, reports HotNewWhipHop.

Reportedly, Kanye has vented about the fashion industry not accepting him on many occasions.
