Jay-Z showcased a new track from his forthcoming 'Blueprint 3' album last night during a surprise appearance at the Summer Jam concert in New Jersey.

The rapper wowed the sold out crowd at the Giant's stadium with 'D.O.A (Death of Auto-Tune)'.

It was the first time Jay-Z had performed the song live since it premiered on US radio last week.

Summer Jam also featured performances from Lil' Kim, Busta Rhymes and Method Man.

But it was Jay-Z's special appearance alongside Young Jeezy that stole the show at the annual event.

As previously reported, Jay-Z is due to release 'Blueprint 3' on September 11, eight years after the release of the first album in the trilogy.

The record has been produced by fellow hip-hop star Kanye West.
