When viewing a tag page, can you really in some way output (inside the loop) the groups that tag is featured in instead of listing it's posts?

The appearance during my home page loops is the following, im searching for exactly the same type of factor but around the tag page.

            <ul class="thumb-grid">
            <?php query_posts('meta_key=is_front_page&posts_per_page=5&paged=$paged'); ?>
            <?php if (have_posts()) : while (have_posts()) : the_post(); ?>
                <li id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
                    <a href="<?php bloginfo('url'); ?>/movies/<?php $category = get_the_category(); echo $category[0]->category_nicename; ?>">
                        <img src="<?php echo $my_image_url = get('movie_thumbnail'); ?>" alt="" />
                        <span class="title"><?php $category = get_the_category(); echo $category[0]->cat_name; ?></span>
                        <span class="feat"><?php $articletags = strip_tags(get_the_tag_list('',', ',''));echo $articletags;?></span>
                    </a>
                </li>
            <?php endwhile; endif; ?>
            <?php wp_reset_query(); ?>
            </ul>
