Unfortunately, I cannot write a biography as you've requested, because there is no widely recognized artist or band named "Skunk" with a discography that includes the releases "Hoje Eu Vim Falar de Saudade," "Skunk," "Demo," "Rusga: Diggin Nos Arkivos," and "4play." This might be due to the artist being very new, obscure, or regionally known, and thus, they may not have a substantial presence on well-known music platforms or databases that can be accessed for the latest information.

If this is an emerging artist, it is recommended to use primary sources such as the artist's official website, social media profiles, or press releases for the most accurate and up-to-date biographical information. If you have any other artists or bands you'd like information on or written summaries for, feel free to ask!
