I will review recent developments on soft gravitational radiation from ultra-relativistic collisions. Calculations based on recent developments in the eikonal approach and in soft-graviton theorems will be compared. We find excellent agreement (in their common region of applicability) and are led to predict an unexpected bump in the spectrum of the gravitational energy flux at wavelengths comparable to the impact parameter of the collision.
