Flu is a musician that emerged from the underground rock scene of Porto Alegre (the capital of the Southernmost state of Brazil). In 1986 Flu joined 'De Falla', one of the most influential Brazilian rock bands. With 'De Falla' Flu (at that time Flavio Santos) recorded six albums, toured throughout Brazil and played big rock festivals, like Hollywood Rock, 1993, sharing the stage with Red Hot Chilli Peppers and Nirvana among others. In 1999, after quitting 'De Falla', Flu has released his first solo album on 'Trama Records' (the Brazilian record company responsible for the distribution of Matador and Sub Pop): '…e a alegria continua' ('…and the happiness continues'). On this album Flu presents songs mixing electronica, bossa nova, and psychedelic rock. To be able to perform the album live, Flu brought together musicians to form the band 'Os Dubem'.
In 2001 Flu participated on the album 'Comp', a compilation by the independent label 'Muquifo Records', contributing the songs 'Suellen' and 'Volache'. In 2002, the song 'Kianka' was selected for the compilation 'National Collection' by the hip-hop label 'Instituto/YB'.
In 2003, Flu’s second solo album came out: 'No Flu do Mundo' ('The World's Flu') ,released by 'Instituto/YB' and distributed by 'Trama Records'. Flu also did many remixes for traditional Brazilian musicians as well as movie soundtracks – e.g. 'City of God'.
Currently, Flu participates in the 'Projeto Pixinguinha' a yearly collective tour that congregates the most important musicians that are active in Brazil – in the previous years names like 'Tom Ze', 'Baden Powell' among others participated in this musical 'caravan'.
