Ditto all this talk, re: Emeralds, OPN, Expo 70, etc. There's been a variant on the old 'kosmische music', gene-spliced with 80s synth music & 'new age' (whatever the hell that means, now or then) that a number of young whippersnappers have ingested and expunged into something of a 'faux hommage', if you will (not an entirely accurate description), but is really a compositional/artistic mandate and conscious directional interest/choice. General synth music seems to be attempting to break free of genre ghetto confines, becoming, in certain stubborn alt.rock & indie quarters, 'respectable'. It is a movement I embrace wholeheartedly and welcome enthusiastically.
Other than saying how much I enjoy the work of Emeralds & OPN, I would further add to this list the likes of Keith Fullerton Whitman, whose love of electronic/synth music is encyclopedic & equally passionate in its scope, and whose recent Moog drone symphonies have been something to behold (quick plug: he'll be performing @ OTP in 2011); Dolphins Into the Future, more on the quieter but no less vital side; plus Dylan Ettinger, Ethernet (who released a brilliant debut disc earlier this year on Kranky), Raglani, Jonas Reinhardt, Venus Vulture, etc. Many of these artists are releasing on vinyl only, and, in some cases, cassettes (which completely mystifies me, and does something of a disservice to their (potential) audience, but, whatever...) As always, reimagining the past, built for the future!
