The guitarists of NYC

Earl Slick has had a long and storied career playing his own music and joining with the likes of David Bowie and Ian Hunter among many others. This Guild ad pictures Slick with fellow guitarist Kevin Russell holding the Liberator and Detonator models and intones the pair’s band NYC. I can find no information about this group. Anyone?
