Lupe Fiasco is working with one of the Linkin Park's personnel, while Jay-Z is hooking up with U2's vocalist and Swizz Beatz.
Recent earthquake in Haiti, which killed more than 200,000 people and injured many others, has made musicians uniting to raise funds to support the victims. Both Lupe Fiasco and Jay-Z have entered studio to craft songs for Haiti.
Lupe, who climbed mount Kilimanjaro along with Jessica Biel and Emile Hirsch to raise awareness for the world's water crisis earlier this month, teams up with Linkin Park's Mike Shinoda in the studio project. As for Jay-Z, the rap mogul joins forces with U2's Bono and Swizz Beatz.
"Last night we wrote a song - Bono got a call from a producer, Swizz," guitarist The Edge said during a radio interview. "He and Jay-Z wanted to do something for Haiti. So, Bono came up with the phrase on the phone, and last night we were here, we wrote a song - finished, recorded, and send it back to them. So, that might be the next thing you hear from us!"
In addition to recording songs for Haiti, Bono will also perform at a benefit concert dubbed "Hope for Haiti" on January 22. According to one of the gig's hosts George Clooney, the vocalist will sing alongside Justin Timberlake, Christina Aguilera, Alicia Keys and Sting.
