'Perfectionist' Jacko would not approve of new album, says family

The late King of Pop's nephew, TJ Jackson, who along with his brothers Taryll and Taj formed the pop group 3T, insists his late uncle was a "perfectionist" and would not be happy with the collection of new material being released without his final seal of approval.

Speaking of the album, which sees eight unheard tracks released on May 13, TJ told the Sun newspaper: "I have mixed emotions because as an artist and as his nephew I know he'd want a final listen before anything he did was released to the public.

"Saying that though, that's my uncle and I want him and anything associated with him to be successful."

Michael's label Epic Records announced last Monday that they would release the new tracks from the late singer's vaults with music executive L.A. Reid lining up producers to "contemporise" the record.

Fans have been reassured the album will only be helmed by producers Jackson had worked with in the past or expressed a strong interest in collaborating with.

Timbaland has been named the lead producer, while Rodney Jerkins, Stargate, Jerome 'Jroc' Harmon and John McClain have also worked on the project.
