We study how black hole superradiance appears in string microscopic models of rotating black holes. In order to disentangle superradiance from finite- temperature effects, we consider an extremal, rotating D1-D5- P black hole that has an ergosphere and is not supersymmetric. We explain how the microscopic dual accounts for the superradiant ergosphere of this black hole. The bound 0< m Omega(H) on superradiant mode frequencies is argued to be a consequence of Fermi- Dirac statistics for the spin- carrying degrees of freedom in the dual conformal field theory. We also compute the superradiant emission rates from both sides of the correspondence, and show their agreement.
