He is primarily identified with the house music scenes in his hometown of Chicago, and San Francisco, California.

Shortly after Farina became friends with Derrick Carter in 1988 at a record store in Chicago, he developed an interest in house music.

[1] Fans embraced Farina's downtempo style, and he started in 1992 a weekly Mushroom Jazz club night in San Francisco with Patty Ryan.
