O Rappa is a musical collective from Rio de Janeiro that blends together a number of varied styles including rock, funk, hip-hop, reggae and samba to create a unique sonic amalgam. Founded in 1993, the group's songs are typically filled with lyrics about social problems occurring in Brazil. Though the group has released a steady supply of albums, beginning with its self-titled debut LP in 1994, O Rappa is primarily known for its high-energy and bombastic live performances.
