Universal Music Indonesia managing director Anthony Shih will leave the company in September after 15 years' service to launch his own independent company.

The still-unnamed management and production venture will focus on artist management and music marketing.

Sandy Monteiro, senior VP, Universal Music South East Asia, will assume responsibility for the company's operations following Shih's departure.

"I've spent most of my professional career with Universal Music, and the time has come to venture into my own business," Shih said in a statement. "I'm looking forward to continuing my relationship with Universal Music with my new company."

Shih joined Universal Music Indonesia in 1993 and was appointed managing director in the same year. His most notable achievement was in signing and developing SamSonS, crowned Indonesia's best pop group at the 2006 Anugerah Muzik Indonesia (AMI) Awards.

The self-titled debut album by SamSonS has crossed the 700,000 units mark to date, and yielded more than 2.8 million downloads of ringback tones, according to the label. Shih was also instrumental in breaking international acts such as Bon Jovi and Shania Twain in the largely domestic product-dominated market.

"Anthony's commitment to Universal Music and our artists in Indonesia is unparalleled," added Max Hole, president, Asia Pacific Region, Universal Music Group International. "Despite the loss, we're delighted in maintaining a relationship with him through his new venture."
