in Boston. She first began looking for a record deal by sending her demos to major record label offices throughout Chile with no success. She performed English-language songs at bars and clubs in Santiago, but eventually began writing and performing in Spanish. After many unsuccessful attempts at signing with a major label, Valenzuela decided to release her music independently in Chile. In 2006, Valenzuela unofficially released her first solo single, "Peces", which she wrote at age 13 about a boy she liked who did not reciprocate her feelings. Within a few months after its release, "Peces" gained popularity on Chilean radio. "Peces" was recognized by Rolling Stone magazine in Chile, as one of the best 100 songs of the year 2006. Due to the success of her first unofficial single, Valenzuela began recording her debut album in Santiago. Brothers Mauricio and Francisco Durán of Los Bunkers produced the album. In December 2006, she released her second single, "Dulce", which reached number two on Chile's national charts. To add more achievements to her short musical career, on May 19, 2007, she was invited by Julieta Venegas to open her concert at Teatro Caupolicán. On June 30, 2007, her debut album, Muérdete La Lengua was released in Chile. The Chilean press quickly dubbed her as The Princess of Rock, calling her,"[a] new musical revelation". Soon after its release, the album was certified as Gold in Chile. Valenzuela performed in New York City at the annual LAMC conference in July 2008. This was Valenzuela's first musical exposure in the US and gave her an opportunity to showcase her music outside of Latin America. To promote her debut album, Valenzuela performed at various venues across Chile, as well as Mexico, Argentina, and other countries throughout Latin America. 2009–2012: Buen Soldado In early 2009, Valenzuela began the pre-production stages for her second album in Santiago and Berlin.

She has also participated in the album tribute for Violeta Parra, recording a new version of "Run Run Se Fue Pa'l Norte" as well as recording a version of Inti-Illimani's song "Vuelvo". In 2009, she collaborated with Chilean rapper, Latin Bitman for his album Colour; Valenzuela co-wrote and sang two songs, "Help Me" and "Someday".
