The parties happen from monday to sunday (except on Tuesday) and the DJs mix indie rock, pop-rock, black music, funk, hip hop, samba, brazilian popular music, drum and bass, raggae and breakbeat (see basic program).
Going to Casa da Matriz means having a different experience. Most of the time you may be the only “gringo” (gringo = someone from another country) in the place. Except on mondays (indie rock) and wednesdays (raggae, breakbeat) where your are going to find a lot of people to talk to in your own language!
