Mirabilis is the neo-classical/ethereal musical project formed in 2001 by Dru Allen of This Ascension and Summer Bowman of the Machine in the Garden. Dru and Summer are the core members of Mirabilis, but they use the project as an avenue to bring in other like-minded artists as guest performers to create something that is extraordinary and unique. In December of 2003, the band's first release, a limited edition 7-inch self-titled EP was released on Fossil Dungeon. They quickly followed up with a full-length debut CD in 2004 on the Middle Pillar Presents label.
