Born in Seattle, Yoon Ahn started her career studying graphic design at the University of Boston, where she met Verbal who was studying Philosophy and Marketing.
Shortly after leaving Boston in 1998, Verbal debuted in M-Flo and began his career in the music industry. Ahn prompted Verbal to replace his traditionally hip-hop baggy clothes for brands he loved like Raf Simons and Dior Homme, in a move that has been said to have spearheaded the movement of hip-hop artists engaging in the concept of high-fashion brands. Quickly the couple started to play around with ideas with some jewelry designers they knew in Tokyo and then stores began to ask them to buy their desi- gns.
In 2002, the duo created Ambush Design Company as a design outlet for Ahn, under which she designed album artwork for a number of artists, including Verbal. In 2004, they founded a couture jewellery line called Antonio Murphy & Astro.
In 2008, they established their second line, Ambush, which was an instant success. Initially designing giant gold chains, gold metal chokers and handmade gold chain-mail hoodies, the line quickly develo- ped more conceptual themes for each collection, such as ‘Nomad’ or ‘Holy Mountain’. Their A/W 15 collection was shown outside of Japan for the first time at the Joyce Gallery in Hong Kong.
