Andrew Gregory Sega (/ˈsiːɡə/ SEE-gə; born May 20, 1975),[1] also known as Necros, is an American musician best known for tracking modules in the 1990s demoscene as well as for composing music for several well-known video games.

Andrew Sega was born on May 20, 1975, in Providence, Rhode Island[citation needed] and lived the majority of his young life in Upstate New York.

[5] Sega later helped form the legendary tracking group Five Musicians, which featured other notable figures, such as Jeroen Tel, Basehead and Hunz.

In 2020, Sega and Alex Virlios (Blue Images, CTRL, Exit) formed Hallowed Hearts and released their debut album Into the Fire.
