We show here that a purely kinetic approach to the excitation of waves bycosmic rays in the vicinity of a shock front leads to predict the appearance ofa non-alfvenic fastly growing mode which is the same that was found by Bell(2004) by treating the plasma in the MHD approximation. The kinetic approach wepresent is more powerful in that it allows us to investigate different modelsfor the compensation of the cosmic ray current in the background upstreamplasma.
