  The chiral magnetic and vortical effects denote the generation of
dissipationless currents due to magnetic fields or rotation. They can be
studied in holographic models with Chern-Simons couplings dual to anomalies in
field theory. We study a holographic model with translation symmetry breaking
based on linear massless scalar field backgrounds. We compute the electric DC
conductivity and find that it can vanish for certain values of the translation
symmetry breaking couplings. Then we compute the chiral magnetic and chiral
vortical conductivities. They are completely independent of the holographic
disorder couplings and take the usual values in terms of chemical potential and
temperature. To arrive at this result we suggest a new definition of
energy-momentum tensor in presence of the gravitational Chern-Simons coupling.
