Lauryn Hill has announced plans for a new single. The 'Doo Wop (That Thing)' singer will release the track 'Black Rage' in the autumn, reports Pitchfork. Hill explained that the song is about "the derivative effects of racial inequity and abuse". The rapper has yet to release a follow-up album to her critically acclaimed debut The Miseducation of Lauryn Hill in 1998. Her last new song was 2010's 'Repercussions'. Hill will also join Nas on some dates of his upcoming 'Life is Good' tour from next month. "I've been a long-standing rebel against the stale, over commoditization," Hill continued in a statement. "As artists we have opportunity to help the public evolve, raise consciousness and awareness, teach, heal, enlighten and inspire in ways the democratic process may not be able to touch. So we keep it moving."
