As you can see, this album is divided into 4 parts, each with an intro/interlude and two real tracks, and all tracks are named after colours. That's quite a nice concept, and the 4 different parts actually have different styles. The first part is the best, with good atmosphere and nicely constructed melodies. The 2 middle parts are more acid and noisy, and the last part goes back to the more melodic side of it.
The last track "Goldfish" contains a hidden track, some minutes of calm chillout music. So this track isn't really 13 minutes but rather 2 different tracks (there's even some seconds of silence between).
Overall, this is not essential, but good, and the style is varied. 6/10.
