Kanye West stuns with new tracks

Kanye West left audiences with their jaws "literally dropped" when he unveiled some new tracks at the weekend.

The rapper has been concentrating on his collaborative studio album Watch the Throne with fellow hip-hop star Jay-Z of late.

Kanye has also been working on some new material of his own, and has already released two singles from his GOOD Music compilation album, Cruel Summer.

The superstar unleashed some new tunes at the Dream Downtown hotel in New York City on Friday to "stunned" party goers.

"He was dressed in black pants and a leather T-shirt," an onlooker told the New York Post adding that Kanye "danced and lip-synced" to his songs.

"The room looked stunned. People were standing around with jaws literally dropped."

Kanye unveiled the tracks after hanging at a table with Leonardo DiCaprio, Erin Heatherton and acclaimed director Todd Phillips.

The 35-year-old star reportedly "pulled out a laptop and headed to the DJ booth" to show off his new music to lucky onlookers.
