Soldiers of Sunrise

Soldiers of Sunrise is the first album by Brazilian heavy metal band Viper, released by Rock Brigade Records in 1987. It was re-released by Massacre Records in 1992 and re-released again in 1997 by Paradoxx Music in a 2-in-1 edition with the Theatre of Fate album. In 2013, through WikiMetal, a new edition was released, including the six songs of the Killera Sword demo tape as bonus tracks.

In a 2013 interview, when commenting on the recording of the album, vocalist Andre Matos said:

The whole record was done basically in a week. It was like, 'One, two, three, go,' and the whole background was recorded almost live. Then there were some overdubs for the solos and stuff, and then it was my part to do the voice in two or three days. And I remember the last days my voice was completely ruined. I had no technique at all back then, and I completely ruined my voice. I had to record this last song called 'HR,' which translated means 'Heavy Rock', and we were even thinking about calling somebody else to sing it because I was not able to sing a single note. But then we said, 'Ah, we can do it a little bit more punk rock like,' so I could sing with my rough voice, which I was able to let go at that moment.
