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.
