Kanye West showcases new songs at Facebook convention – video

Rapper admits feeling 'moments of doubt' in album build-up

Kanye West has showcased a series of songs from his new album ‘Good Ass Job’ at Facebook‘s headquarters.

The rapper performed the verses of three new songs – ‘Lost In The World’, ‘Chain Gang’ and ‘Mama’s Boyfriend’, which you can watch below – a capella for a group of the social networking site’s employees at Palo Alto in California.

Speaking about his performance afterwards, he wrote on his blog kanyeuniversecity.com: “To all my friends at Facebook, many times in life I’ve had to deal with moments of doubt. And as it’s been a minute since I’ve performed any fresh material in front of an audience, this could’ve been one of those moments… but it wasn’t. Your energy was a gift so electric, so genuine, that it really helped me give my best. The energy was so inspiring I had to keep going! I just hope you got as much from me as I got from you…which was everything!”

The follow-up to 2008’s ‘808s And Heartbreak’ will be released in the US on September 14, with a UK release expected on September 13.

Last month the first potential single from the LP, ‘Power’, which features Dwele and samples King Crimson‘s 1969 song ’21st Century Schizoid Man’, leaked online.
