Description
I will review recent work on the near-horizon perturbations of nearly extremal Kerr black holes. These perturbations experience transient growth, resulting in a "ring up" to strongly enhanced amplitudes. These transient instabilities connect directly to the slowly growing instabilities of extremal horizons, and may have observable consequences.
