Gamma-ray bursts from Kerr black holes are expected to be luminous in gravitational radiation powered by the spin-energy of the black hole [van Putten & Levinson, Science, 295, 1874 (2002)]. The Brown scenario of GRB-hypernovae (and their remnants in soft X-ray transients) hereby describes a contemporaneous and unbeamed explosion shell, consistent with GRB 011121 and GRB 011121 and GRB 011211. This suggests considering upcoming wide-angle supernovae surveys to guide future LIGO/VIRGO searches for bursts in gravitational waves. If all long GRBs stem from hypernovae, the expected hypernova-to-supernova ratio is about one in a few hundred in the local universe. Events for which the energy E and frequency f in these gravitational wave emissions satisfies the compactness criterion 2π ∫ f dE > 0.005 will provide an existence test of Kerr black holes.
