Devil Child is a solo project that was established by Marco Simmer, largely known as the frontman for the American alternative metal troupe Osmosis. He decided to embark on a solo career in the spring of 2006, wanting to take a bit of time off from extensive touring with his primary group. Under the Devil Child alias, he tends to perform via a variety of instruments with a sound firmly rooted in electronic music.
Since inception, Simmer has released four full-length albums and five extended plays; his third studio album featured Lukas Crimbrook, Simmer's stepbrother, who contributed drums to all but two songs on the record.
