Auris Apothecary is a Bloomington, IN based label which dabbles in most obscure formats imaginable. Forget the CD, the LP and the cassette (well, they do releases on those formats, but only sometimes!), these motherfuckers release their stuff on 8-tracks, reels, floppy discs, microcassettes, "anti-cassettes", unspooled reel tapes. For all I know, they might have stuff coming on LaserDisc, Betamax or even wax cylinders. Thankfully, if you don't have a reel machine or a 8-track player, you can listen to the music from the label in handy digital format. The archive is available on the label's Bandcamp page. And while I'm at it, let me post the best release (and the longest one, clocking at 60 minutes) - a microcassette by Deep Magic.
