Jay Z and Angie Martinez

After jumping ship at Hot 97 for Power 105 in June, Angie Martinez is kicking off things with a bang at her new home — Jay Z.

The hip-hop mogul called in with a message for the radio personality.

“I really believe that what you are about to accomplish in the next phase of your life will dwarf everything that you’ve ever done,” Jay said. “Because, that’s what people who are great do. You’re not termed ‘the voice of New York’ for no reason. You’re an institution in radio. That’s a pretty special feat to accomplish.”

Martinez added her own message about her first show on Power, saying: “I made minimal mistakes. I’m very proud of myself.”
