  In this talk we elaborate on a mechanism to generate local contributions to
the curvature perturbation in isolated patches of the Cosmic Microwave
Background (CMB). The mechanism, based on the generation of an
out-of-equilibrium configuration in fluctuating scalar fields of mass $m\sim H$
during a sustained stage of fast-roll inflation, has been recently shown to be
capable of accounting for some of the most robust large-angle anomalies
detected in the CMB. In this talk, we show in detail how the embedding of the
mechanism into models including vector fields can result in the breaking of
statistical isotropy in isolated patches of the CMB.
