Very beautiful gem of post-rock here. Rooted in the classical sound of mono-explosions in the sky of two guitars, bass and drums, the music moves you within several emotional realms. The musicianship and recording quality are excellent. The mood is very much in the Mono vein of nostalgic/apocalyptic sadness. The drummer remembers me easily of the explosions in the sky's drummer with his heavy use of martial snare drumming.
Some tracks (mainly "3x3+2" and "Rien pour l'instant") remembers also me of Kid-A/Amnesiac epoch Radio-head.
My favourite song of the EP is "Scorpion Rouge, avec Dolph Lundgren", because the beginning is more light/upbeat and less doomy overtly dramatic.
Apart from being short in size, the only criticism I have on this disc is that music gets VERY predictable at times, following all the overused clichés of post-rock such as obvious crescendos and explosions (very much in the Mono fashion), specially on tracks "Lichen A" and "Rien pour l'instant").
Overall, a very pleasant and thoughtful album that sets for a very enjoyable listen. Keep up the good work!
