The nonlinear instability mode of a monochromatic wave in a medium with an inertia-free non-linearity is analyzed theoretically and simulated numerically. It is shown that, if longitudinal and transverse instabilities occur simultaneously, the wave is splitinto three-dimensional clusters containing amplitude singularities. As a result, the monochromatic wave "breaks down," which is accompanied by a considerable widening of its spectrum and angular divergence.
