US rapper Jay-Z will release 'Blueprint 3' on September 11, according to US reports.

The album is the third in the rapper's Blueprint trilogy, which began on the same date eight years ago.

Full details about 'Blueprint 3', which has been produced alongside fellow hip-hop star Kanye West, will be officially unveiled on Sunday.

But it is thought the album will be released in a joint venture between Jay-Z's Rock Nation label and Warner following the rapper's recent departure from Def Jam.

As previously reported, West recently described the album as “amazing” and revealed he had been asked by Jay-Z to remove all auto-tune.

The recording technique, which makes the performer sound robotic, dominated West's last album '808s and Heartbreak'.
