Gaby Koss (born 25 March 1978 in Munich, Germany) is a German classically trained soprano who has collaborated with metal and rock acts such as Haggard, Nota Profana and Equilibrium.
She took private singing lessons with the vocal teachers like Dietrich Schneider, who has instructed singers including Tölzer Knabenchor.
[1] She was part of the symphonic metal act Haggard from 1998 to 1 September 2004, when she was fired due to personal disagreements.
In 2013, she recorded the new full-length production of the band, The Devil's Playground, in which she displayed a more ethereal style in the song The Grove.
Koss is being instructed by the teacher and tenor Saverio Suarez Ribaudo in Munich and collaborates with several bands and with composers for film and TV-Series soundtracks.
She is also a singer for the band Doninia, where she sings in different styles ranging from very ethnic and dark vocalizations to the classical technique she usually uses.
[citation needed] She has developed in several singing styles and techniques to create what she calls "different voices", and right now she is working with her current teacher with tenorina (female tenor) repertoire.
