The release works much like any other label compilation, highlighting Oslo's core artists as well as a few newcomers, but with one significant twist: there's no way to know which artist did which track. According to a press release, this is an attempt to put the focus back on the DJ, while at the same time allowing listeners to "fully immerse themselves into the mix without prejudice."
That's an interesting approach. I usually look at the mix tracklist to get a feel what about to listen to. This changes things a bit.
