The coupling of the shear Alfven wave and the drift compressional wave is studied in a two-component plasma. It is shown that with the incorporation of delB particle drift in the dispersion equation the cold component in addition to reducing the Alfven speed to create an unstable drift compressional wave, also plays an important role in the coupling of the mode to the shear Alfven wave resulting in major modification of the instability.
