Controversial rap group Odd Future's upcoming Pitchfork Music Festival appearance in Chicago, Illinois will bring out the protesters on 17 July (11) - activists from a women's rights group plan to make sure Tyler, The Creator and his band know they don't approve of their misogynistic lyrics.
The hip-hop collective has upset members of rights group Between Friends, who plan to peacefully protest at the festival and hand out information and resources aimed to counter violence against women.
They're not the only group offended by Odd Future's musical message - bosses at the Gay & Lesbian Alliance Against Defamation (Glaad) have blasted frontman Tyler for his controversial rhymes about rape and murder and insist homophobic slurs he has published on Twitter.com are "inexcusable".
Spokeswoman Kimberley MCLeod writes, "Tyler has said in interviews that he is not homophobic, yet his Twitter feed and rhymes are rampant with anti-gay slurs and references. His defense that 'people take things too seriously' or that he's 'just a kid' is inexcusable.
"Using hateful language, regardless of the context, is unacceptable and in fact, very serious. Tyler's attempts to be provocative as well as his indifference towards the consequences of his actions are irresponsible."
Glaad's criticism came just days after Tegan and Sara pop/rock star Sara Quin published an open letter urging music journalists to condemn Tyler's "sickening" and "hateful message".
