College, in Grellier's words, was an attempt "to synthesize into my music the emotions of my childhood" and was greatly influenced by American 1980s pop-culture, "80's soaps and an aesthetic which I particularly like: color, images, silvery films and the sun – images of Los Angeles, Chicago and all of the other cities that [...] continue to fascinate me" as well as artists including Daft Punk, Alan Braxe, Fred Falke, Lifelike, Jacques Lu Cont, Nicolas Makelberge, DJ Falcon, and John Carpenter.

The Valerie Collective described as "responsible for some of the very best original electronic music now coming out of France", was created as a way to foster musical talent, by providing opportunities for collaboration among artists, also connecting them through blogs and other internet channels. The collective is characterised by a "retro-futurist", "romantic blend of 1980s inspired electro" or synthwave.
