1) Adagio is a French neo-classical progressive band hailing from Montpellier, France, formed in 2000. Stephan Forté, the band's guitarist, is considered the creative force behind Adagio. Adagio's music is characterized by technical precision, dark, dense orchestration, complex lead work, and a driving rhythm section.
