Kendrick Lamar preparing to release new single ‘i’

Rapper has revealed the single's cover via Twitter

Kendrick Lamar has announced the release of new single ‘i’.

The rapper took to Twitter today, simply posting the letter ‘i’ and what appears to be artwork for the release. Billboard reports that the track is scheduled to be released to radio on Tuesday (September 23), while sources have told Rap-Up.com that it will feature a sample from classic soul funk group The Isley Brothers.

‘i’ will likely feature on Lamar’s next album, the follow up to his 2012 major label debut ‘Good Kid M.A.A.D. City’.

Earlier this month, it was reported that the 27-year-old is facing legal action from jazz musicians Eric Reed and Willie Jones III following claims of plagiarism. The onetime members of former jazz ensemble Black Note are suing Lamar over his alleged use of their music in his 2011 song ‘Rigamortis’, claiming the material was taken directly from their 2010 track ‘The Thorn’.

The duo are suing Lamar for at least $1 million (£613,000) and are seeking profits and all rights to ‘Rigamortis’.
