**450 copies** Rotorelief presents a reissue of Alésia Cosmos' Aéroproducts, originally released in 1985, with bonus material. In the '80s, Alésia Cosmos was one of those pioneering groups that invented a handful of things: uprooted electro, pop-shifted funk. With some synths, rhythm boxes, magnetic tapes, crazy guitars and hallucinated voices, they rocked the underground for four years, with two albums, playing live in France and Europe. The dazzling epic of the magic combo has become legendary in the margin of new European music. The first LP, Exclusivo!, was self-produced in 1983 and marked the beginning of the association between Bruno de Chenerilles, Pascal Holtzer, and Marie-Berthe Servier who constituted the hard core of Alésia Cosmos. Forming an underground label, mail order, and radio station, the three musicians were also activists in the musical underground so fertile in the '80s. In 1985, the second album Aéroproducts was published by the Swiss label Hat Hut Records. Recorded, produced, and designed by the group, the object to the three photos captured in the windows of the Musee Zoologique de Strasbourg, was not quite a double-LP, because it contained only three sides of recorded music. In early 2017, the Californian label Dark Entries reissued Exclusivo! and Rotorelief engaged in a longer process of new production for Aéroproducts. In 2018, the discovery in the group's archives of intact multitrack analog tapes coming directly from the studio sessions used for Aéroproducts, allowed a remixing and a new mastering, with some new versions and bonus tracks, produced just before or after the period of activity of Alésia Cosmos.
