The second PASSPORT album continues building upon the solid foundations of the debut. "Mandragora" is a nice melodic opener with prominent use of electric piano/clavinet and of course Doldinger's wild sax. More aggressive "Nexus" is interesting for a short bass pedal works (wah-wah). "Fairy Tale" is a slower tempo, gentle theme with very good bass lines although sax gets sometimes too improvised. "Get Yourself a Second Passport" contains some nice unison bass and electric piano parts.
This album found Klaus Doldinger ditching the old lineup, so effectively a brand new Passport. This album is a mixed bag, there's a couple of numbers that throw you over the edge, and several experiments that are untypically Passport. Much of the Latin influence of Iguaçu is gone here, some of the songs here leans towards the instrumental Alan Parsons Project side of things, one electronic piece, couple that sounds like classic Passport, and a couple of more lightweight numbers. By the way, Ataraxia and Sky Blue are the same release. For some strange reason, Atlantic Records in the States felt it would be better titled Sky Blue, while the international release is called Ataraxia.
Funk and world-music prevail on Iguaçu (1977), which thus marks an abrupt change of direction. The influence of Embryo is a mixed blessing, as the torrential rhythms and dance grooves detract from the lyrical moments of the previous two albums (partially salvaged in the less "worldly" Iguaçu).
Infinity Machine, another impressive collection, adds a spiritual touch to the proceedings (Blue Aura, Ostinato Contemplation), while the tight playing and the lyrical production keep the music beyond the standards of jazz-rock (Morning Sun). At the same time, the longest jam, Ju Ju Man, shows an even stronger funk element.
This psych funk/jazz record from 1973 has a line up including Curt Cress, Kristian Schultze and Wolfgang Shmid, with the composing and arranging done by Ace Saxeman and Klaus Doldinger. "Hand Made" showed progress, at least in terms of a more personal sound, and contains Abracadabra and Hand Made.
