Beastie Boys member Adam Yauch, best known by his stage name MCA, is staying punk even in the afterlife. According to the late rapper's will, neither his image nor his music will be allowed to appear in advertising.

"Notwithstanding anything to the contrary, in no event may my image or name or any music or any artistic property created by me be used for advertising purposes," read Yauch's will, which was filed with the New York County Surrogate's Court in Manhattan this week, according to Rolling Stone.

It is unclear whether the relevant provision of Yauch's will extends to all of the Beastie Boys' creative output. Yauch collaborated strongly with the other Beastie Boys members, Michael Diamond (Mike D) and Adam Horovitz (Ad-Rock).

The will also names Yauch's wife Dechen Wangdu as the sole executor of his estate. Yauch's assets of $6.4 million were left to Dechen and the couple's daughter, Tenzin Losel Yauch.

In May, Yauch succumbed after a long battle with cancer, only a few months following the release of the Beastie Boys' last album, "Hot Sauce Committee Part Two." Yauch was 47.

The Beastie Boys publicly announced Yauch's cancer after it was diagnosed in 2009. While the group was planning the recording of "Hot Sauce Committee," Yauch's cancer forced the trio to shelve the project for some time and cancel several tour dates.

In life, Yauch was fiercely concerned with keeping the Beastie Boys image uncommercialized. He once rapped, "I won't sell my soul for no TV ad," and, true to the spirit of the song, the Beastie Boys have kept a tight rein on their work. In fact, the surviving members are defending it in court right now.

On Wednesday, Diamond, Horowitz, and Wangdu sued the makers of the Monster energy drink over unlicensed use of music by the Beastie Boys, the Associated Press reported. According to representatives of the Beastie Boys, Monster used its music to create a 23-minute promotional video without the permission of the artists.
