The idea of forming the band was at the end of 2000. After a long time looking people to be part in this project, Ch'aska was finally formed at the beginning of 2002. The first live performance was in Arequipa, in June 2002. In December 2002, the band took part in a rock & roll contest organised by a local radio station, with many bands of different genres. Ch'aska won the contest obtaining as prize the recording of two unpublished songs. Then, in February 2003, Ch'aska released a demo entitled with the same name of the band, including two tracks: "Sweet Lover" and "Imperio Caído". The demo allows the band to act in many different cities of Peru. Ch'aska performed in some cities like Lima, the capital of Peru, one of those shows was a Chuck Schuldiner Tribute that was an official event. Besides, in early 2005, the band performed in Arica - CHILE, and also was invited to be an opening act to Sepultura in La Paz - BOLIVIA. In the middle of 2005, CHASKA was invited for co-conducting a special for the band in a local TV program, so the band made a home video for the track, "Imperio Caído". In the middle of 2007, the band presented in its site on MySpace and in a promotional CD, two new tracks: "Bicolour Cannibalism" and "Tuta Ch'aska", as advance of its debut album, Pururauca.

In 2009, the band released its debut full-length CD entitled "Pururauca", this album was produced by the Peruvian indie label, Mythic Metal Productions.

Ch'aska could be described as a folk metal band, because the band mixes heavy metal with some folk elements from Peru.
