Haggard has by far been the band to perfectly meld metal and classical into one thing. While bands likes Symphony X, Children of Bodom, Stratovarius, ect. have integrated classical styles and techniques into metal guitar, Haggard presents a more accuracte, complete picture of what classical should like. Their music is incredibely well-arranged and its great diversity - distinctively death metal vocals, somber piano lines, crunching guitars, choral-like female vocals, grand,emotive, and epic orchestrations. Check them out.
