  We study the propagation of energy density perturbation in a hot, ideal
quark-gluon medium in which quarks and gluons follow the Tsallis-like momentum
distributions. We have observed that a non-extensive MIT bag equation of state
obtained with the help of the quantum Tsallis-like distributions gives rise to
a breaking wave solution of the equation dictating the evolution of energy
density perturbation. However, the breaking of waves is delayed when the value
of the Tsallis q parameter and the Tsallis temperature T are higher.
