Yoko Ono, Sonic Youth's Kim Gordon and Thurston Moore to release mini album

The six track album will be released on September 24 and will feature the 14 minute long single, "Early In The Morning", reports Rolling Stone.

In October last year Gordon and Moore announced their split. The rock couple released a statement through their label Matador Records revealing that they were separating after 27 years of marriage.

The announcement raised doubts over the future of Sonic Youth after Matador revealed that plans for the band remained "uncertain", even though they had previously hinted they would record new material in 2011. The statement read: "Musicians Kim Gordon and Thurston Moore, married in 1984, are announcing that they have separated. Sonic Youth, with both Kim and Thurston involved, will proceed with their South American tour dates in November. Plans beyond that tour are uncertain."

Sonic Youth released their 16th studio album The Eternal in 2009, while Moore's third solo album, Demolished Thoughts, came out in May 2011.

Yoko Ono features on a track called 'Do It!' on the forthcoming collaborative Flaming Lips album, The Flaming Lips And Heady Fwends, which also features Bon Iver and Nick Cave.
