 nAbstract\nFor a compact Riemannian 4-manifold\, the Bach tensor is a mult
 iple of the gradient of the Weyl energy functional. This symmetric 2-tenso
 r is conformally covariant and fourth-order in the metric\, and vanishes f
 or any metric conformal to an Einstein metric. Thus finding a Bach flat me
 tric can be thought of as a generalization of the Einstein equation.  In m
 y talk I'll review the basics of a geometric flow by the Bach tensor and t
 hen report on ongoing work concerning stability of the flow in various set
 tings.\n
