The hearty main ingredients in the compilation Comfusoes 1 are Angolan pop songs from the ’60s and ’70s. These shimmering nuggets of Afropop are given extra spice by a bunch of Brazilian producers, who update them for modern ears—and in some cases the dance floor—with beats and embellishments that honor the music rather than simply chopping it into bytes. It’s heady and historical all at once, a strange and beautiful stew garnished with the mellifluous Portuguese language that the two countries share.
