'Quadropus' is the third full length album by Estradasphere. It was released on October 28, 2003.For Quadropus, Estradasphere made a conscious decision to isolate the genres for each track, instead of including many genres in a single song. For example, "Mekapses Yitonisa" doesn't stray far from its Greek gypsy roots while "Crystal Blue" is purely Beach Boys-esque rock music.
