Michael Jackson will reportedly release a new single and album ahead of his comeback shows in July.

The singer has written 'hundreds' of songs since his last LP in 2001 and plans to premiere new music before his residency at London's O2 arena.

"There will be a new Michael Jackson single before the first date," concert promoter Randy Phillips confirmed.

"Michael has got some new music and he is looking for a new way of disseminating his material to his fans."

Promoters AEG suggested that the star may give away a brand new album to fans at his shows, a measure used by Prince in 2007.

The 'This Is It' concerts, which kick off on July 8, are expected to feature state of the art visual effects throughout the planned 90-minute shows.

"He wants to use some technical effects that have never been seen before."
