For many, Infinity Machine is the last Passport album worth your time. Certainly that same lineup was augmented with the Roy and Elmer Louis (presumably brothers) and some Brazilian musicians, and recorded Iguacu, which finds them doing Brazilian-influenced fusion (although the album could have easily included tango rhythms as well given Iguacu or Iguazu Falls goes through Argentina as well as Brazil). Curt Cress (to join New Triumvirat for the album Pompeii), Kristian Schultze, and Wolfgang Schmid had left, with Roy and Elmer Louis from the 1977 lineup still remaining (and Klaus Doldinger) with brand new musicians. Ataraxia, known as Sky Blue in the States is that album, and I found it rather underrated. It's not perfect, and it's not as great as Cross-Collateral, but several songs really took me by surprise. They take on a more spacy electronic approach on some of the cuts, like the two part title track, and a really interesting electronic piece called "Reng Ding Dang Dong". I never hear Passport do anything like this piece, an amazing little piece of electronic music, sounded like Doldinger didn't want Passport to stagnate. Two songs are clearly in the instrumental Alan Parsons Project vein with "Sky Blue" and "Loco-Motive". "Mandrake" sounds like typical Passport of the time, but the album is not perfect as I felt "Louisiana" is too close to smooth jazz, and the Brazilian-influenced "Alegria" (which could have easily fit on their previous album) seems a bit tacky. It's obvious to my ears that Klaus Doldinger wanted both creative ambition and mainstream acceptance, and it shows on this album. I was rather surprised by this album despite the flaws.
