Neuronium is a Barcelona, Spain based electronic music group. It was founded in 1976 by keyboardist/synthesist Michel Huygen, keyboardist/synthesist/guitarist Carlos Guirao and multi-instrumentalist Albert Giménez. This lineup released two albums for EMI-Harvest, "Quasar 2C361" in 1977 and "Vuelo Quimico" (Chemical Flight) in 1978.
With the departure of Giménez the group continued as a duo but was joined on their third album, "Digital Dream" (1980), and their fourth album, "The Visitor" (1981), by guest guitarist Santi Pico. After the release of the fifth album, "Chromium Echoes" (1982), Guirao departed. Since then Neuronium has become synonymous with Huygen, either solo, with Santi Picó, or with guest musicians. On most albums released between 1983 until 1996 Neuronium was the duo of Huygen and Picó with both musicians listed as full members. Four Huygen solo efforts were released under the Neuronium name during that time as well. Picó also returned for an appearance on the album "Alienikon" (1999) and for live performances in 2008.
Huygen has termed Neuronium's music as "psychotronic music" and "cosmic electronic music". Neuronium (Huygen and Guirao) collaborated with Vangelis on the album "A Separate Affair", recorded in 1981 and released in 1996.
