Sandra Nasić (born 25 May 1976) is a German singer of Croatian descent who is the lead singer of the rock band Guano Apes. After graduating from college she planned to study Art and Design. But one night in 1994 at a university party the other three members of the future band spotted her. Not long after some discussion she started rehearsing with them. Nasić was originally introduced to the band by a friend who wanted their opinion on a singer he`d discovered for his own project. According to guitarist Henning Rümenapp, the band "stole" her from him, though they remain friends.
In 2001, she was given an EinsLive Krone award for Best Singer. After Guano Apes completed a brief farewell tour in support of their greatest hits package Planet of the Apes in February 2005, she announced a solo career (signing with her former Apes` label Gun) with her debut album released on 29 October 2007. She was also a guest vocalist on the Apocalyptica song "Path Vol.2". In 2009, she and the rest of Guano Apes reunited.
