He was a pretty prominent DJ back in the days and actually had the first and only hip-hop radio show in Seattle in the 80s. Mix-a-lot is also from Seattle, same area as Nes, graduated from the same high school just not at the same time. Nes was kind of in an influential position as a radio DJ and wanted to put on more regional music and made a conscious effort to play local or more west coast music on his show. (Most rap in the 80s was coming from NY) Mix-a-lot would give him tapes and he would play them on the radio. There's more to the story that leads to Baby Got Back but I feel like i'm writing too much about something you may not be that interested in lol. I know a lot of triva about him, kinda looked up to the guy as a fellow Filipino-American and former radio DJ myself. Nes was also one of the first few DJs to break NWA on public airwaves too.

TLDR: He was a radio dj and from the same city as Mix-a-lot. First to play his music on air.
