Originally formed in 1994 as an all-instrumental, power metal outfit, Italy's DGM featured guitarist Diego Reali, keyboardist Maurizio Pariotti and drummer Gianfranco Tassella.
In springtime 2001, Andrea Arcangeli (Airlines Of Terror, Solisia, Concept, ex-River of Change) became the new DGM bass player just before the Italian dates for Dreamland promotion.
After the split of former member Maurizio Pariotti, Hidden Place was released in May 2003 with different sound from the new keyboard player Fabio Sanges (Abstracta).
Mularoni and Casali gave the new songs a renewed process of recording and the result of Simone's experience is included in Different Shapes, which was released in 2007.
