After the exploit of Osmose in 1978, Kalma returns into the studio in 1980 with Interfrequence, an ambient space library record. Interfrequence is a continuation of his personal research based on the combination of electronic machines with natural sounds and acoustic instrumentation. The french musician fully wears the robe of master of ceremonies of the synths. However, the path taken is not that symphonic of the minimalist and galactic suites composed by other standard bearers like Richard Pinas and Klaus Schulze. Here, we find 18 short pictures sound (few of them in collaboration of M. Saclays) that emanate a variety of ideas and ethno-cultural influences unparalleled. A distinctive compositional style always returns an crescendo of ecstatic emotions, a reflection on the hidden and secret aspects of the micro and macro cosmos. If in Osmose the sampling sound from the mother Gaia was more explicit, here the Nature is investigated not only in terms of pure tones, but especially in the dynamics of flows and movements dictated by the frequency of moogs and organs and embellished with hyper-space flutes, saxophones and clarinets. Kalma wrote yet another chapter of his personal saga of a new world of sound imagery.
