  We determine holographically 2-point correlators of gauge invariant operators
with large conformal weights and entanglement entropy of strips for a
time-dependent anisotropic 5-dimensional asymptotically anti-de Sitter
spacetime. At the early stage of evolution where geodesics and extremal
surfaces can extend beyond the apparent horizon all observables vary
substantially from their thermal value, but thermalize rapidly. At late times
we recover quasi-normal ringing of correlators and holographic entanglement
entropy around their thermal values, as expected on general grounds. We check
the behaviour of holographic entanglement entropy and correlators as function
of the separation length of the strip and find agreement with the exact
expressions derived in the small and large temperature limits.
