With their seventh album, the German group Passport embraced the innovative sounds of Caribbean jazz and funk, influenced by the melodies of mainstream, commercial smooth jazz. The lineup that entered the recording studio for this album, titled after the waterfalls located on the border between Argentina and Brazil, consisted of Klaus Doldinger (saxophone, organ, and synthesizers), Curt Cress (drums), Roy Louis (guitar), Wolfgang Schmid (bass), and Elmer Louis (percussion), along with a number of Brazilian percussionists such as Wilson Das Neves, Pedro Santos, Marcello Salazar, Noel Manuel Pinto, and Clélio Ribeiro. Tracks with a distinct Caribbean/African flavor, such as "Sambukada" and "Iguaçu", alternate with the jazz-funk of "Aguamarinha", "Guna Guna", "Heavy Weight", and "Praia Lame", and the jazz fusion of "Bird of Paradise". In short, “Iguaçu” is another excellent jazz fusion/funk/rock album released in the 70s.
