O Trio is a choro group which includes been giving a significant contribution for the introduction of the custom. O Trio does not have any percussion, rather they depend on two of the very most experienced choro players in Brazil and an internationally granted classical blowing wind musician (also a fantastic chorão). They’re looking for some sort of versatility that withdraws from folklore, but manages to maintain their music deeply psychological and faithful towards the choro genre while absorbing erudite affects. In 1986, Maurício Carrilho (violão or classical guitar), Pedro Amorim (mandolin/violão tenor), and Paulo Sérgio Santos (clarinet, soprano/alto saxes) teamed up to celebrate Radamés Gnattali’s 80th wedding anniversary. After shows in European countries, U. S., and Japan, they documented their first recording, O Trio (released in European countries in 1993), that was praised by critics and received the 1994 Clear prize as greatest instrumental record. O Trio also gained the 1994 Clear prize as greatest instrumental group. In 1995 O Trio documented an album associated Teca Calazans.
