Vanilla Ice vs Queen & Bowie

Vanilla Ice became a household word for a whilebecause of the copyright infringement that occured in 1990 when it came to light that he had sampled Queen and David Bowie’s “Under Pressure” without consent or license. Ice Ice Baby hit number one on the charts in the United States and Vanilla Ice became the one ‘under pressure’. Vanilla Ice altered the rhythm of the baseline thinking he would thereby avoid any question of credit, royalties, license or even permission. This case never went to court as it was clear that Vanilla Ice had stolen the sample without permission. He settled out of court with Queen and David Bowie for an undisclosed but very likely very high amount. Ice Ice Baby has been released in many different versions, since then, with all of the legal procedures followed.
