Clearly, this brother duo reps the early, sentimental end of romantic sertaneja ( look at that album cover: those mullets! that cowboy hat!). These two sweet-talking caipiras helped herald the Brazilian country genre’s entrance into mainstream popular music in the ‘70s and ‘80s with their tightly coiled harmonies and plaintive cowboy love songs. From the country-pop waltz “Adeus Solidao” to the mariachi-laced “Amor a 3” to the passionate folk of “Obras de Poetas,” Chitãozinho & Xororó sob through every nuance of love, breaking your heart a million times. Schmaltizily swoon-worthy.
