Head Control System is a cross-national rock/metal band featuring Portuguese Daniel Cardoso (ex-Sirius and ex-Re:aktor) and Norwegian Kristoffer Rygg (of Ulver and ex-Arcturus and ex-Borknagar).
Head Control System is currently part of North-American The End Records' roster along with bands such as Voivod, The Gathering, Sleepytime Gorilla Museum and Ulver.
Its first release was the EP "Severe Damage on Reason and Equilibrium" — the acronym identical to the capital letters of the band logo.
While Daniel himself never wrote a single lyric, he did, however, implement his ideas for the EP in collaboration with André Vasconcelos, a friend and writer.
Being influenced by the likes of Meshuggah and the work of Fredrik Thordendal himself, Daniel Cardoso uses rhythms and cycles in a melodic style of rock, bearing some resemblance to Tool, Faith No More or A Perfect Circle.
