Sandhy Soendhoro, better known by his stage name Sandhy Sondoro, sometimes stylized as Sandhy SonDoro, (born 12 December 1973) is an Indonesian singer-songwriter. He is best known for winning the 2009 International Contest of Young Pop Singer New Wave, in Jūrmala, Latvia.

Sandhy was born in Jakarta, Indonesia, as Sandhy Soendhoro,^[1] to Rr. Rika Pudjihastuti and Achmad Fauzan. Sandhy is of Palembangese, Javanese, Buginese, and Minangkabau descent.^[1]

Sandhy came from a musical family, where the house provided the likes of American pop, folk, jazz, and blues tunes coming from his mother's or father's guitar every day. His cousin, Ira Maya Sopha, was a famous child singer in Indonesia during the 1970s.^[2]

After graduating from high school in Jakarta, at the age of 18 Sandhy went to visit his uncle in California and stayed there for a while, before leaving for Germany to study architecture.

In Germany, he joined a band on his campus, but they rarely appeared on stage. Later he decided to find a job as he lived alone there and needed to support himself. He had an opportunity to work in a supermarket but didn't get the job, as he was too late. On the way back to his apartment on his bike, he saw a busker on the street and asked if he could join him. The busker agreed and Sandhy borrowed his friend's guitar and started playing on the streets of Biberach an der Riss. They got 50 deutschemarks in an hour and shared the money. They played three times a week before he decided to do it alone.^[3]

In 1998 he moved back to Berlin and started singing and playing the guitar in bars, clubs, and metros. His famous song "Down on the Streets" was inspired by the experience gained in Berlin metros. He also performed in famous theatres like the House of World Cultures in Berlin, and at music festivals such as the Bode Museum Isle Festival In 2005, Sandhy performed in a charity concert for the 2004 Indian Ocean earthquake and tsunami victims, "Berlin for Asia."

During his time in Germany Sandhy "changed" his last name from "Soendhoro" (new spelling: Sundhoro) to "Sondoro" because many people had difficulties pronouncing it. He also explained that Sondoro means "The Sound of Gold" in Latin. On his birth certificate and other official documents, his last name remains as "Soendhoro."^[1]

Sandhy found a wider audience through Stefan Raab's casting show, a popular segment within one of Germany's most successful late-night shows SSDSDSSWEMUGABRTLAD .

On 25 April 2008, he published his debut album Why Dont We, after releasing his first single "Down on the Street" earlier.

The 2009 New Wave ran from 28 July to 2 August 2009 and was contested by 16 singers from 12 different countries. Sandhy was the first Indonesian, and also the first Southeast Asian to participate.
