  We show that in a layered metal, the angle dependent, finite frequency,
interlayer magnetoresistance is altered due to the presence of a non-zero Berry
curvature at the Fermi surface. At zero frequency, we find a conservation law
which demands that the `magic angle' condition for interlayer magnetoresistance
extrema as a function of magnetic field tilt angle is essentially both field
and Berry curvature independent. In the finite frequency case, however, we find
that surprisingly large signatures of a finite Berry curvature occur in the
periodic orbit resonances. We outline a method whereby the presence and
magnitude of the Berry curvature at the Fermi surface can be extracted.
