Problem: Madonna's initial music videos reflected her American and Hispanic mixed street style combined with a flamboyant glamor. She was able to transmit her avant-garde downtown New York fashion sense to the American audience. The imagery and incorporation of Hispanic culture and Catholic symbolism continued with the music videos from the True Blue era. Author Douglas Kellner noted, "such 'multiculturalism' and her culturally transgressive moves turned out to be highly successful moves that endeared her to large and varied youth audiences." Madonna's Spanish look in the videos became the fashion trend of that time, in the form of boleros and layered skirts, accessorizing with rosary beads and a crucifix as in the video of "La Isla Bonita".
She transmit her avant garde style to which audience?

Answer: American audience
