This work talks about the far-out concert costumes from Japan's music-loving teens. Japanese rock bands are gaining international attention, but local fans have followed their favourite bands for years. Girls dress up in unique fashion styles when they attend J-Rock concerts, making the audience almost as much of an event as the music. Their outfits express their individual feelings and convey the excitement of the music they love. This book is a visual collection showing some of the hot and absurd groupie fashions created by fans of today's most popular J-Rock bands.
