Description
Recently there was significant progress in account for several lower
harmonics of the ``Little Bang", especially the so called triangular flow,
ascribed to fluctuations of the initial conditions. We discuss this
problem more generally, combining many harmonics coherently into
certain patterns of sound propagation. Analytic solution for all harmonics
is found for the so called ``Gubser flow", with complete Green function
obtained. Another source of perturbations
which can be studied using our results are waves induced by quenching jets.
We argue that for large energy loss shock waves should form, as well as
the so called jet/fireball edge, separating unperturbed and excited matter.
We discuss how this edge should be visible experimentally, perhaps on \
event-by-event basis.
