SEOUL, March 18 (UPI) -- Hyo Jin Moon, the oldest son of the Rev. Sun Myung Moon, founder of the Unification Church, died of a heart attack in Seoul. He was 45.

The younger Moon, who died Monday, was born in South Korea and grew up in the New York area, a church statement said.

He ran Manhattan Center Studios, a New York multimedia facility used by musicians and orchestras for recordings and broadcast events. He was also the founder of MC Korea and MC Japan.

Moon was a musician, performer and multimedia executive producer, producing more than a dozen albums and creating a composition catalog numbering in the thousands. He continued to perform during concerts in Asia each spring up until his death.

Before running Manhattan Center Studios, Moon worked for a decade as first president of the World Collegiate Association for the Research of Principles.

Moon spoke regularly during Sunday meetings in upstate New York, drawing on his experiences for a particular topic. His last speech, "Commitment," was delivered March 9 before he left for South Korea on a business trip.

Moon is survived by his wife, Yun Ah Choi, and four children, and five children from a previous marriage.
