That is a pretty special record, a big part in my mind because of Jon Hassell and that feel of wind across the desert that he gets with his horns. Adds something almost intangible, yet gives it a realism that wouldn't be there otherwise. He worked again with Baaba Maal (one of the voices on Passion) and Brian Eno on the 12-minute closing track "Lam Lam" on Maal's Nomad Soul, and it has some of that same feel, the desert winds blowing from a distance. Really amazing. Worth it for that trip at the end if you can find a cheap used copy, because the rest of it is more traditional Afro-pop.
Have you listened to much Brian Eno? Hassell and Eno worked together on the amazing Ambient 4: On Land from the early 80s, probably the darkest and most fulfilled (for me) of the Eno ambient series. Brilliant record, and easily on a par with the Gabriel soundtrack, probably very influential on him. It doesn't have the background voices, or quite the Middle Eastern setting, but has some of that same feel. Here's some words from Amazon ...

Released in 1982, On Land is Eno's most mature, perfect ambient work. Combining low, rumbling synths with eerie banging and clanking and the occasional wild-animal chirp or grumble, this recording places the listener alone, in the midst of a massive piece of sonic landscaping. And Eno has left no detail to chance. In fact, the work is so complete that when Eno suggests a windswept plain, the listener gets a chill. When trumpeter Jon Hassell bays with a softly disturbing imitation of a wounded beast, the first instinct is to scan the horizon for its glinting eyes. So subtle, intuitive, and well paced is this recording that as it slips quietly from the speakers and into every corner of the listening room, it transforms the space into a gently pulsing sound environment that seems strangely out of time and away from everything. It's a place you'll be drawn to time and time again. An ageless masterwork. --S. Duda
Another great record is the mid 90s Night Song by Nusrat Fateh Ali Khan who was also one of the voices in the background on Passion. Michael Brook is the sound architect, who also has worked a lot with Gabriel and Eno. Has kind of a trip-hop feel to it, yet Khan's vocals are amazing. More words from Amazon ...

Canadian experimental guitarist Brook and the late, "shining star of Qawwal" come together for a second time to bring the music of Pakistan into a creative new realm. If you are a traditionalist who wants nothing but Pakistani music, stay away. This album is soaked in ambient electronic guitar noises and some of Khan's most out-of-the-tradition singing. These experiments are not to be confused with lots of the electro-noodling, however. Both artists were devoted to their gods and their music, and it shows in the potency of these tracks. Brook seems to have been a natural match for Nusrat and has drawn out an unusual performance that probably fulfills the ideas that were only hinted at in their first collaboration, Musst Musst. --Louis Gibson
