Big fan of their Ukranian folk album "Chi no Hibiki Higashi Yuroppu wo Utau", it's a jewel for programming (apart from THAT track).
It's precisely via Gamelan, which led me to Akira OST gamelan sounds, that I've discovered Geinoh Yamashirogumi (which then led to Muslimgauze, tangentially)
I just listened to the video you linked to. It seemed promising, but the lead flute was too much of a distraction for me. Perhaps after more hours of listening it wouldn't be such a problem.
The repetitive, gentle sounds put me into a high efficiency mode without putting me to sleep like most ambient.
