Derdian is a power metal band from Milan, Italy. 'Henry Pistolese' and Marco Covelli founded the band in 1998 and initially intended it to be a thrash metal style. The two founders were joined in this project by Luigi Trapani (vocals/guitar) and Samuele Carrari (bass). They began by covering bands like Metallica and Megadeth. However, at some point they began writing original songs with more of a power metal sound, a change which influenced Luigi and Samuele to leave the band. Read more on Last.fm
