tax-title.php

<?php

global $post;
$trm = get_post_type($post);
$taxonomies = get_object_taxonomies($trm);

$terms = wp_get_object_terms( $post->ID, $taxonomies[0] );

foreach( $terms as $term ):
    $term_names[] = $term->name;
    $stageName = implode($term_names); // you'll need to add an argument here if artists appear on more than one stage
endforeach;
