  We study a variation of Kac's question, "Can one hear the shape of a drum?"
if we allow ourselves access to some additional information. In particular, we
allow ourselves to ``hear" the local Weyl counting function at each point on
the manifold and ask if this is enough to uniquely recover the Riemannian
metric. This is physically equivalent to asking whether one can determine the
shape of a drum if one is allowed to knock at any place on the drum. We show
that the answer to this question is ``yes" provided the Laplace-Beltrami
spectrum of the drum is simple. We also provide a counterexample illustrating
why this hypothesis is necessary.
