Rap-metal band Linkin Park wants out of its contract with Warner Music Group on the eve of the company's initial public sale of U.S. stock.

The multi-platinum group's management company said it had become "increasingly concerned" Warner Music's "diminished resources will leave it unable to compete in today's global music marketplace," the Los Angeles Times reported Tuesday.

In response, Warner Music said Linkin Park's complaint was just a bid to get more money out of the company as it readies to file for an initial public offering.

"While Linkin Park's talent is without question. The band's management is using fictitious numbers and making baseless charges and inflammatory threats in what is clearly a negotiating tactic," Warner Music said Monday.
