[PAR] [TLE] Triosphere [SEP] Triosphere is a Norwegian heavy metal band from Trondheim, Norway, created in 2004 by singer and bassist Ida Haukland, and guitarist Marius Silver Bergesen.  They are defined by their heavy metal sound emphasising their power metal-like melodies and choruses, while also featuring progressive elements.  Bergesen is the composer of all instrumental parts, with Haukland acting as lyricist, and composer of the vocal parts. [PAR] [TLE] Progressive music [SEP] Progressive music is music that subverts genre and expands stylistic boundaries outwards.  Rooted in the idea of a cultural alternative, musical progressiveness embodies a continuous move between explicit and implicit references to genres and strategies derived from various cultural domains, such as European art music, Celtic folk, West Indian, or African.  The word "progressive" comes from the basic concept of "progress", which refers to development and growth by accumulation, and is often deployed in numerous music genres such as progressive country, progressive folk, progressive jazz, and (most significantly) progressive rock.
