Kanye West was 'depressed' over Glastonbury performanceLos Angeles, Aug 1 (AZINS) Rapper Kanye West says his headline performance at the Glastonbury Festival in 2015 put him in a "depressed state".

West said it was an humbling experience when he forgot his lyrics and got the music wrong, reports mirror.co.uk.

"It was incredible. I started off the show and I completely messed up the music. And me, as you can imagine by this phone call, I am a bit of a perfectionist," West told BBC Radio One.

"So it really put me into a slightly depressed state, and it put me back in the position of when I was in high school and I got fired from my job, or when I played my music for R Kelly and he told me he was going to sign me, and then three months later I didn't have any money, I couldn't afford a haircut, I couldn't take my girlfriend to the movies and I'm still in my momma's bedroom, working on beats, and I was that close to being signed by R Kelly," he added.

West said that he usually doesn't get "nervous".

"I don't usually get nervous. I prepare, I get fully prepared. When that music messed up in the beginning, it tapped into my nerves and when you are nervous or vulnerable, something special and something different can happen," he added.

The "Gold digger" rapper also outlined why he wants to run for US president, an ambition he announced on stage at the MTV Video Music Awards last year.

"We are numb, we are numb to 500 kids getting killed in Chicago a year," he said.

"We are numb to the fact that it was seven police shootings in the beginning of July ... We are numb to places on the earth that we don't live, like our life is okay but it's okay for other people's lives to not be okay," West added.
