  We introduce a perturbation $h_{\mu\nu}$ onto a background Lifshitz spacetime
and examine some of its consequences. In particular, we consider a radially
localized perturbation and compute the resulting holographic Green's function
to linearized order. At leading order, the Lifshitz Green's function
demonstrates suppression of spectral weight at low frequencies, and this
feature allows bulk perturbations in the IR to be partially hidden from local
boundary probes.
