What is "oslo."

oslo. was a European post-punk band that released recordings on UK label Scared Hitless in 1999. They were notable for stylizing their name as a terminated common noun, distinguishing it from other Oslos such as Spanish band Oslo from 1984, Italian band Oslo in 2003, U.S. band Oslo in 2003, and French duo Oslo in 2013. The concept is similar to the separated type.object.property hierarchy associations used in object-oriented programming and appears on the cover art of album oslo.DAYLIGHT, designed by "karen.j.robins", and on their single oslo.skrika. subtitled skrika...[to scream]. Confusion over the band's name continued for more than a decade at music retailers, cataloguers and auctioneers.
