Been listening lots of Drone Records sub-label 10"s. Subtantia Innominata label focus exclusively for 10" format, but one could say it is pretty much what Drone Records does, just not 7"s. Most of these have duration up to 25-30 minutes, making them long enough to really sink in, but never allow piece to become too much of "the same". When good 10" is in turntable, it is easy to give another spin instantly.
Many of the 10"s are done almost decade ago, but still available for cheap prices. Thanks to big pressings. Regular full color vinyl sleeves, editions usually 500 copies, 10" format. Nothing is bound to be rare - but that's kind of best thing with these. If release wasn't absolute future classic, it will be worth of money nevertheless.
Now playing BRUME "two characters". Yen Pox, (ad)vance(d), Hum, Bass Communion, all were decent listening that I most likely would have not bought as CD - but somehow this 10" series seems almost like could make decision to grab them all..
