Stemage is Grant Henry, a song-writer and arranger from North Carolina. His most notable work is the band Metroid Metal, whose official website is http://www.metroidmetal.com (although he also released most of these songs as solo recordings under the name of Stemage. Note that despite last.fm's redirect, Metroid Metal is a separate artist, being a band consisting of five people, not just Stemage).
Stemage's original work is a combination of pop, metal, and 90's influenced rock. In 2006, he released Strati, a collection of original compositions with vocals.
On January 16, 2011, Stemage released his first video game soundtrack, for the Xbox Live Indie game, Alpha Squad.
Stemage has also released a new original album in August 2011, which contains new songs such as "Three Minutes", "Shut Up and Listen", and "Ground Pink".
