Fundo De Quintal, who emerged out of the Wednesday samba parties on Rio de Janeiro’s Uranus Street in the mid-’70s, have crafted over 20 albums and hundreds of tracks in pagode style. From early numbers such as “Bebeto Loteria” that sound like they were recorded at a party to 2003’s sharply produced “Não Tá Nem Aí”, this much-loved outfit reinvented a genre by introducing instruments like the tan-tan and banjo into classical samba. They’re as influential as they are prolific.
