Between is the name of two groups of artists: 1.) In 1970, Peter Michael Hamel founded BETWEEN, an international band specialised in improvisational / « ethnic » rock music. The name Between comes from the fact that Hamel's music is originaly "in-between", always making a combination between "popular music" and "serious music". The classical musician Robert Eliscu (born American), responsible of oboe parts in POPOL VUH can be considered as the major member of the musical tribe next to Peter Michael Hamel.
