Taxonomy in loop

Hi,
Can anyone please tell me if you have an idea why doesn’t this work :

<?php
$args = array(
	'tax_query' => array(
		array(
			'taxonomy' => 'locations',
		)
	)
);
$query = new WP_Query( $args );	?>
<?php if (have_posts()) : ?>
	<?php while (have_posts()) : the_post(); ?>
		<h2>
		<a href = "<?php the_permalink(); ?>"
		rel = "bookmark" title = "
		<?php the_title_attribute(); ?>"
		alt = "
		<?php the_title_attribute(); ?>"
		>
		<?php the_title(); ?>
		</a>
		</h2>
	<?php endwhile; ?>
	<?php else : ?>
	<h2>Sorry nothing Found</h2>
	<?php endif; ?>

I obviously have created to taxonomy in my functions.php, one of them is called ‘locations’ and I have a few posts connected to it, problem is the loop ignores my new WP_query and shows all of them, if I specify only one term (‘locations’ => ‘vejer’) it does work but I can’t seem to be able to tell the loop to show all posts under ‘location’ when trying to do that I get all posts.
