As a singer-songwriter of numerous lyrics and songs, he is one of the most beloved, and often controversial, icons of the Portuguese rock scene.
He was born in Porto, Portugal and studied at the Lisbon Theatre and Film School (Escola Superior de Teatro e Cinema).
By 1980, GNR started out playing at parochial parties for Carvalhido Church in Porto and other similar events in the area.
Rui Reininho went to a concert of GNR in Pavilhão do Académico (a sports pavilion in Porto) to interview the band and eventually was invited to join the group.
The band had great success in Portugal during the 1980s and early 1990s when they reached a peak of nearly 200 live performances by year.
