Canadian teen-pop singer Justin Bieber, Irish rockers U2 and Barbadian R&B artist Rihanna have signed on to donate songs to a digital charity album to benefit the victims of Japan’s March 11 earthquake and tsunami.
Dance-pop diva Lady Gaga—who already designed a Japan Prayer Bracelet to aid relief efforts—is currently in talks to contribute to the album as well, along with rapper Nicki Minaj and Jersey rockers Bon Jovi.
Universal is hoping to have the album available by the end of the week, opting for an exclusively digital release to get it out as quickly as possible. Proceeds will go directly to the Japanese Red Cross to aid those affected by the staggering devastation. The official death toll from the 9.0 earthquake and tsunami is more than 9,000 but the Japanese media estimates the actual death toll has surpassed 20,000.
