Hey, it's been a while since you published your question. I couldn't find any literature on it and I am interested too. Did you find anything?
scandinavian Nc6+Bg4+0-0-0+e5 ?

It might be worth looking in books on 1.e4 Nc6 because you can obtain the same opening by transposition: 1.e4 Nc6 2.d4 d5 3.exd5 Qxd5

Ah! And you can look for material about the "Jadoul Gambit" or the "Portuguese variation of the center counter" [1.e4 d5 2.exd5 Nf6 3.d4 Bg4]. There is an old book on it by NM Z. Anderson.

In "The Modern Scandinavian" [Müller & Langrock], read chapter 15: "The Viking Centre".
Here the intro to that chapter:
"The Viking centre is characterized by the black set-up . . . Nc6 , . . . Bg4 and . . . 0 - 0 - 0 .
The c-pawn i s left o n its starting square. Just like the Vikings i n their day, Black gets
down to business and goes after his opponent at once. White 's centre is immediately put under pressure and you have to know your way around the sharp variations , because despite the advantage of the first move, a crushing defeat could be around the corner.
However, it is worth noting that Black cannot favourably employ this set-up against all white move orders. It is generally very playable if White holds back with Nc3 ."
i wonder what's the name of the variation in the scandinavian defence where black play Nc6 instead of the tipically c6 and then Bg4 follow by 0-0-0 and e5 puting fast and high presure in white center?, i just playing a game using this plan but i dont know any about this variation
i would like to know if there are books about it if its really good or are refuted or something
