As a percentage of the mix, there are less meditative tracks and not as much deep sound as I usually have. But with a total duration of 4+ hours, there's still a lot of it. Estrogen 23 is full of contrasts and rhythm. There's a lot of upbeat and emotional music, a lot of broken rhythms and rapid transitions, but the overall concept remains unbreakable — these are beautiful melodic tracks, each one complementing the previous one.
