Winner of three Grammy Awards, Kosh is the former art director for Apple Records and designer for many of The Beatles solo projects. His first project at Apple was the design of the "Abbey Road" package. After his Apple days, his clientele expanded to cover the cream of British rock bands including The Rolling Stones, ELO and The Who. He remained close to John Lennon and handled the WAR IS OVER campaign for John and Yoko.
The 1970's brought Kosh to L.A., where he worked with the likes of James Taylor, The Pointer Sisters, The Jackson 5, Cher and Jimmy Buffett. During that time Kosh also won three Grammys for his work with Linda Ronstadt and designed the cover of "Hotel California" for the Eagles. Many of his album designs have been exhibited at the Rock and Roll Hall of Fame Museum. These days, Kosh continues to work with Jimmy Buffett and Linda Ronstadt as well as Lewis Black and Ron White, while also doing graphic design work that includes TV titles, logos and book designs.
