Aguas de Março, Portuguese for Waters of March, was written by Brazilian composer Antônio Carlos Jobim and released in 1972. The song is built as a long list of images associated with the end of summer and the March rains in Brazil, and it became one of the most celebrated works in Brazilian popular music. A celebrated duet version by Jobim and singer Elis Regina, recorded for their 1974 album Elis and Tom, helped it reach a wider audience. Its gentle structure and memorable imagery have kept it popular in films, covers and online edits long after its first release.
