The '212' rapper, who has become embroiled in online feuds with Angel Haze and Perez Hilton in recent months, posted a series of messages accusing the band of trying to interfere with her set yesterday (March 8).
Banks was appearing at the Future Music Festival and claimed that the Stone Roses had deliberately sound checked as she played to the crowd.
She wrote: "Big apologies on behalf of the stone roses to my fans at the festival today.(sic)
"My ex tour manager made a pact with the stone roses saying they'd sabotage my set because I fired him.
"And they decided to check their equipment behind me during my set."
Banks's messages became more aggressive, as she continued: "F**k those old saggy white n***as stone roses. I wish them nothing but excrement and death.
"Wow! I must really f**king be a superstar... You've got an established band trying to sabotage my lil rap bitch shine."
She added: "Wow a bunch of old white men trying to bully a young black girl... What the f**k else is new in this world???"
