The detection and analysis of gravitational wave signals from coalescing binary systems crucially relies on analytic perturbative a pproaches to the two-body problem in general relativity (as well as on num erical approaches). \; While the post-Newtonian (weak-field and slow-m otion) approximation is most directly relevant to observations by LIGO et al.\, recent developments have revived interest in the more inclusive post -Minkowskian (weak-field but arbitrary-speed) approximation -- particularl y in relation to highly advanced techniques developed by particle physicis ts for computing relativistic quantum scattering amplitudes and associated classical observables. \; This interplay between high-energy quantum physics and gravitational-wave science has led to several new results and useful insights\, particularly regarding relationships between complimenta ry approximation schemes\; this importantly also includes the "\;self- force"\; or "\;post-test-body"\; approach\, treating small mas s ratios but arbitrary field strengths and speeds. \; We will review s ome of these developments\, focusing on the post-Minkowskian treatment of the spinning black hole binary problem.
