"Sexual Behavior in the Human Male" is one of The Gerogerigegege's most experimental releases to date, and is pretty ambient and tame compared to their vinyl releases. However, there is still a bit of audio shock in the batter. While you start to doze off to the relaxing "Minamiguchi" song, you will be awaken pretty quickly to the sounds of rioting and chaos on the following song "Symphony For a New Age Destruction." This album has a touch of ambiance in it, but don't be mistaken. The Gerogerigegege still are making a soundtrack for a chaotic fanbase. If you want sheer ambiance, however, "None Friendly" is highly recommended.
