The norwegians do not believe it likely that Modeselektor would add so many "scratch"-sampels if the mix was indeed done digitally :)
As of the mix itself, it's very good both technically and musically. Spanning a lot of genres and constantly changing pace and mood, Modeselektor shows how its possible to mix gabber and NERD. If anyone have heard their Boogybytes vol. 3 mix, it isn't very similar stylisticly, but the philosophy is the same. Thumbs up.

From listening to this, I assume it's mixed digitally. It's flawless and the mix of tunes is eclectic and just downright fun - from electronica to hip-hop to old skool to gabber to breakcore. One of the best party music CD's I own.
