Radio Za-Za! is the first job in Grand Theft Auto 2 given to protagonist Claude Speed by Elmo of the Loonies. The mission is available from the top of the two green Loony phones in Fruitbat of the Downtown District.
The Zaibatsu Corporation have mixed a new drug in with Futuro FM's music and are driving people crazy. This is ruining Loony reputation, so Elmo asks Claude to destroy the generator causing the madness.
Completing the mission will give you $20,000. Futuro FM can no longer be heard in the Downtown District after this mission.
