Here's a great example of creative minimalist design. Black Beast Of Arrrghhh self titled cdr was released by Forever Escaping Boredom. On Bandcamp it's a digital release, and it's credited as a file on Discogs . Simple self printed transparency.. cut, folded and placed in a clear cdr envelope
Three inch cdrs and bizcard cdrs survive in a niche of their own. I attribute that to their novelty. Most people can't walk into a box store and buy a spool off the shelf. If you're not familiar with them, you're in good company, many people aren't. Oubliette -Cold Parties (2006) https://www.discogs.com/release/954973-Oubliette-Cold-Parties
Oni Gosen - 'Oni Gosen' (2004?) Oni Gosen were a band from Grand Rapids, MI around the early 2000's. Nothing more than a myspace page and a few tracks on Last.fm. Absolutely squat on Discogs. Besides being a pretty good band, they released one of their cdr in a hand stitched purse.. ..with tassels Great band and good luck finding anything from them
