Tantri, who has distinctive and husky vocals, has idolized two rock singers, Anggun C. Sasmi and Nicky Astria, since she was a child.[2] In 2008, Tantri became the vocalist of the outgoing Box Pare. Tantri previously started her music with the music group Ares from Jakarta, which was one of the finalists in a band event organized by a private television station, The Dream Band in 2004.
