Since the demise of the chillout room, ambient music has been identified mostly with drones and beatless soundscapes. But in the '90s, Detroit's John Beltran conceived of ambient as something more like techno without the drums. While there were plenty of elegiac pads, rippling arpeggios and pinging guitar tones gave the music an unusual degree of movement and detail. Here, Amsterdam's Delsin label collects his best work. Like much Detroit techno, it's about decay, but it's also about redemption, capturing both the vacant lot and the dewy spiderweb sparkling against the blacktop.
