Andrew Gregory Sega (born 20 May 1975), also known by the pseudonym Necros, is a musician best known for tracking modules in the demoscene in the 1990s. Sega began writing MOD music in 1992 for the demo group Psychic Monks. Through the mid 1990s he contributed music to various demo and music groups, and music disks such as Epidemic (1994), featuring other noted tracker musicians like Purple Motion (Jonne Valtonen) and Skaven (Peter Hajba). Sega later helped form the legendary tracking group Five Musicians, which featured other notable figures, such as Jeroen Tel, Basehead and Hunz. He has also programmed and/or composed music for several demoscene productions, such as the NAID '95 demo Eden and 1996 demo Babylon. Later in his career, he started making music for games, beginning with little known titles such as In Pursuit of Greed, Iron Seed and Xixit, then moving on to Origin Systems' Crusader series. Sega was a founding member of the video game music production company Straylight Productions, contributing tracks to the first-person shooters Unreal and Unreal Tournament. Later, he joined Digital Anvil (now a part of Microsoft Game Studios), and worked as a programmer and musician on Freelancer. As The Alpha Conspiracy, Sega released two albums, Cipher (2001) and Aura (2004), and an album with another artist, the Low Technicians, Forward Rewinding (2002). Sega is currently part of the electro-pop group Iris, and has his own recording label known as Diffusion Records. Due to the "raw" & editable nature of Sega's early compositions, tracked module files were often subject to the practice of "ripping": Persons borrowing sound samples or sequences from Sega's songs & claiming originality in lesser cases, and in more severe cases, persons relabeling entire songs, and possibly modifying author & copyright data within the song file in order to redistribute the song as their own.
