Elton John is among the stars backing the campaign

Other musicians including Carole King, Beck, Sheryl Crow and Eagles star Don Henley have joined in the campaign for a change to the law.

Love had been sued by Universal for refusing to continue recording for them, prompting her to counter-sue the record company, citing "unconscionable" dealings with them.

Love is challenging the legal amendment that was won by the music industry in 1987.

It allows record companies to sue musicians and singers for albums not produced over the course of seven-year contracts.

But record companies say they are not exploiting the artists, who sign the contracts voluntarily.

The suit is expected to go to trial at the Los Angeles Superior Court in June, according to the newspaper.

Concerts

Love is lead singer of the band Hole, widow of Nirvana frontman Kurt Cobain and an award-winning actress.

She and other campaigning artists have formed a group known as the Recording Artists Coalition.

It has the backing of stars including Elton John, Billy Joel, Sheryl Crow and the Eagles, who will stage several concerts before the Grammys to raise money and awareness for their cause.

A US senator, Kevin Murray, has also taken up their fight and has introduced a bill to overturn the amendment.

Love is also involved in a legal battle with Cobain's former Nirvana bandmates over who should have control of the band's music.
