Beastie Boys star Adam 'ad-Rock' Horovitz is expected to testify in the band's copyright infringement case against Monster Energy Drink this week (begs26May14).

The rapper, Mike Diamond and their bandmate Adam Yauch's widow, Denchen Yauch, filed a suit against the company in 2012, claiming bosses had used a number of songs, including Sabotage and Make Some Noise, in a promotional video at the Ruckus Festival in Canada without permission.

Horovitz is scheduled to appear appear at Thurgood Marshall United States Courthouse in New York City on 27 May (14), when he'll represent the Beastie Boys, who are seeking financial damages of $150,000 (Gbp94,000) for each infringement, as well as a permanent injunction.

In their suit, the band's lawyers state, "The public was confused into believing that plaintiffs sponsored, endorsed and are associated with defendant Monster in promoting defendant Monster's productions and promotional events".

The court battle comes just months after the Beastie Boys settled a copyright infringement suit over the use of their song Girls in a viral ad for toy firm GoldieBlox.

Company bosses issued an apology to the group, published in small print at the bottom of their website, admitting they should have contacted the band before deciding to use the song in their advert.
