Santiago Arroyo (GoG) was born in 1980 in Madrid (Spain). He started his musical career in Metal and Rock bands at the age of 14.

Being a self-taught musician, but having studied musical language and music theory, in 1998 he joined some extreme metal bands to consolidate a more solid career and give his first concerts sharing the stage with bands of international prestige.

He has been a live drummer for several bands during the early 2000's as well as in orchestras performing all over Spain.

He is currently a member of bands such as Avulsed, Holycide and Buriality, although he combines this work as an independent musician for recordings and concerts.
