Biography
Biography
Boyd Kosiyabong was born on 5 September 1967, the third of five children. Having great interest in animated cartoons and music, he started taking piano lessons by the age of four but soon had to give up formal lessons which could not satisfy his specific interest in cartoon soundtracks. He became self-taught afterwards, learning to play the theme songs of his favourite cartoons and beginning to compose by the time he was in sixth grade. He had wished to study animation, but being unable to do so he followed the path of his other interest, music. He studied song writing, electronic music and music business at University of California, Los Angeles. Early in his career he worked as a freelance songwriter for musical artists and advertising. After a few years, he joined Kamol Sukosol Clapp, Somkiat Ariyachaipanich and Salinee Panyarachun in founding Bakery Music, an independent music label, in 1994. Among the first of the label's acts was Modern Dog, which quickly proved successful. Boyd was widely noted for his roles as composer and manager of Bakery Music. His compositions were mainly romantic and inspirational songs, such as Seasons Change, which topped the charts upon its release in 1995 and later became the namesake of the 2007 film of the same name. With the rapid growth of Bakery Music, Boyd began expanding investments into the other businesses, founding the animation studio Be Boyd Characters (now Be Boyd CG) in 1997, while partner Somkiat created the Dojo City label, which catered to young female audiences, and Bakery Music also expanded into publishing, with the magazines Katch and Manga Katch. However, the company later faced management and economic issues, and was acquired in 2000 by BMG, which in turn merged with Sony Music Entertainment to become Sony BMG in 2004. At this point, Boyd, along with the original founders of Bakery Music, left the management, while Bakery Music remains today as a sublabel of Sony. Boyd and Kamol Sukosol Clapp then formed a new partnership and created a new label, Love Is, in 2004. Kamol later left to work in other businesses, and Love Is was restructured as a production house company.
