  We consider a one-frequency, quasi-periodic, block Jacobi operator, whose
blocks are generic matrix-valued analytic functions. We establish Anderson
localization for this type of operator under the assumption that the coupling
constant is large enough but independent of the frequency. This generalizes a
result of J. Bourgain and S. Jitomirskaya on localization for band lattice,
quasi-periodic Schroedinger operators.
