post e custom post type in the same query

Hello, I want to know how it’s possible doing a query that returns posts and posts under custom post type. This is my code, but it doesn’t work.

$args = array( 'posts_per_page' => 4, 'post_type' => array('post', 'programacao-vila'),
        'tax_query' => array(
            array(
                'taxonomy' => 'eventos',
                'field' => 'id',
                'terms' => $atts['term']
            )
        ),
        'cat' => $atts['cat'], 'order' => 'DESC');
$wp_query_slide = new WP_Query( $args );

thanks
