We report here the first results of the spectral and timing analysis of our simultaneous INTEGRAL/RXTE observations of GRS 1915+105. The first observation ever performed with INTEGRAL revealed a new class of variability, where changes of luminosity seem driven by changes in the Comptonising medium. The spectro-temporal study of our data taken later, in the steady state, could show the influence of the compact jet in the hard X-rays.
