Tamba Trio were a Brazilian jazz group more commonly praised for their jazz instrumentals than for their vocals. Their vocals on this track are nice and simple, but it is the instrumentation and arrangement which really make the song. What does it sound like? I do honestly like other types of music, but here goes: jazzy piano, bossa beat, thick strings, group vocals. Really great track, and from what I've heard of other versions, they really transformed this song, which normally sounds very different.
