We prove a new perturbation criteria for frame sequences, which generalizes previous results and is easier to apply. In the special case of frames infinitely generated shift-invariant subspaces of L-2(R-d) the condition can be formulated in terms of the norm of a finite Gram matrix and a corresponding rank condition.
