Roy Sugihara is a producer and engineer from West Los Angeles, California. He took classical piano lessons as a boy. A middle school affair with Coca Cola's  cokemusic.com introduced Roy to music production. In turn, Roy got turntables and a mixer. He ordered used hip-hop and dance records from eBay. That became expensive for the boy. Roy’s affection for growing technologies such as Serato’s Scratch Live would lead him to become his high school's DJ. 

DJ’ing brought a passion for songs, and Roy’s interest in production was sparked. He read on various topics: production, engineering, music history. He grew up in Ableton Live. He found a number of recording artists in his circle, working on projects for free, honing his chops. With his friends, he released mixtapes called “Hot Tapes,” releasing tracks over a six month period. Two of the tracks found airplay at European radio.

After graduating UCLA, the Internet would bring Roy to Chilitos Valenzuela and his Audiograph International. Currently, Mr. Sugihara is AGI’s Ableton Live instructor and a very valuable asset for the company.
