This occurred in parallel with developments in Cuba The first Cuban band of this new wave was Irakere. Their "Chékere-son" (1976) introduced a style of "Cubanized" bebop-flavored horn lines that departed from the more angular guajeo-based lines which were typical of Cuban popular music and Latin jazz up until that time. It was based on Charlie Parker's composition "Billie's Bounce", jumbled together in a way that fused clave and bebop horn lines. In spite of the ambivalence of some band members towards Irakere's Afro-Cuban folkloric / jazz fusion, their experiments forever changed Cuban jazz: their innovations are still heard in the high level of harmonic and rhythmic complexity in Cuban jazz and in the jazzy and complex contemporary form of popular dance music known as timba.
