an idea that hasn’t been en vogue for a while, for probably a collection of reasons. See also: postrock. But styles of music don’t die; they wait for someone to do something good with them. That doesn’t mean resurrection from the not-trendy void by any means, but it doesn’t not mean that. Alexander Trust, aka Miguel Sabogal of the also somewhat retro-leaning electronic/a duo Polygons, is doing something here worthy of downtempo/IDM’s ancestors and of your ears. Maybe part of it’s the distinction between mood music and “something else” that put something of a hurt on downtempo back in the day, and what elevates Sabogal’s new work. It doesn’t drag, doesn’t take your chill-state for granted, assuming rather that you want to listen to new and interesting music. Dig, for example, the sly metamorphosis of one particular melodic theme in “Radio Sweetheart (Follow Me)” from synth cloud bank to blue-sky piano over the course of a few minutes, leaving you moved from after-party to head perked up in a small recital hall of rapt listeners. Very nice. Strangely enough, Sabogal explains in an e-mail that this EP is a culled-down version of a longer LP finished this summer.
