How to display the User Avatar, relationship CPT and User

Hi,

I am using the following code to display the title and thumbnail for relationships between 2 CPTs 'event' and 'music' :

function test_ref() {
   $connected = new WP_Query( [
    'relationship' 	=> [
        'id'   		=> 'event-music',
        'to' 		=> get_the_ID(),],
        'nopaging'		=> true,
] );
while ( $connected->have_posts() ) : $connected->the_post();
    the_post_thumbnail( array(80,80) );
    the_title();
endwhile;
		wp_reset_postdata();
};

I have setup a relationship from User to Post, the ID is event-band, it is not reciprocal. I want to display the name and profile/avatar of the user(band). How do I have to change the above code
