  Quantum anomalies give rise to new non-dissipative transport phenomena in
relativistic fluids induced by external electromagnetic fields and vortices.
These phenomena can be studied in holographic models with Chern-Simons
couplings dual to anomalies in field theory. We perform a computation in
AdS/CFT of the anomalous transport coefficients in a holographic massive
gravity model, and find that the anomalous conductivities turn out to be
independent of the holographic disorder couplings of the model. To arrive at
this result we suggest a new definition of the energy-momentum tensor in
presence of the gauge-gravitational Chern-Simons coupling. We also compute the
electric DC conductivity and find that it can vanish for certain values of the
disorder couplings.
