Both "Das Vergessene" and "Keep Your Eyes Closed" progress in a similar fashion: they creep into earshot, barely announcing their presence, all the while slowly seducing you with their never-ending now. Guentner's productions always move, though they may move very slowly, but his great talent lies in his capacity to confuse your perceptions of pace and progress: at any point, "Das Vergessene" feels static, but there's just enough detail in the undergrowth. In that respect, Guentner reminds a little of, say, Robert Wilson's choreography, which is so austere and mesmerically paced you barely notice bodily movements as they happen.
Guentner isn't nearly as austere as Wilson, of course. I'd imagine that foremost in Guentner's aesthetic is a dedication to creating music that's sensually captivating. "Keep Your Eyes Closed" is a particularly good example: Drifting out on two wistful, helium-high drones that co-exist happily, without tension, Guentner slowly introduces bell-like tones that ping and glint in the dusk breeze, softly striking one another like wind chimes. A simple premise, maybe, but that simplicity is the key to Guentner's Pop Ambient productions: Find a few elements, slowly encourage them to play together and then let them alone to see what eventuates.
