QUATRO A ZERO presents the latest breakdown of a musical genre that has over 150 years of history in Brazil: the “choro”. The group proposes a new perspective within the style laying the foundations on tradition associated with freedom to use elements from other musical universes, from jazz to classical music, from samba to other kinds of Latin American music. The group expands the boundaries of this genre by proposing an innovative instrumental set up in its context (electric guitar, piano, electric bass and drums) and with extensive use of improvisation. In its 8 years of existence, the group has released two acclaimed CDs and has participated in the most important cultural projects of the country.
