There are several problems within your configuration.

You should change the way you register your controllers. It is now only registered as an invokable with the string you've given. It is not registered by its FQCN as you try to use it within your route configuration. Nevertheless you use the wrong FQCN within the route config. You are using Controller\Album::class but the class is called: AlbumController so change that to Controller\AlbumController::class.

This is what your config should've been looking like:

return array(
    'controllers' => array(
        'aliases' => array(
            'Album\Controller\Album' => Controller\AlbumController::class
        ),
        'factories' => array(
            Controller\AlbumController::class => \Zend\ServiceManager\Factory\InvokableFactory::class,
        ),
    ),

    'router' => array(
        'routes' => array(
            'album' => array(
                'type'    => 'segment',
                'options' => array(
                    'route'    => '/album[/:action][/:id]',
                    'defaults' => array(
                        'controller' => Controller\AlbumController::class,
                        'action'     => 'index',
                    ),
                    'constraints' => array(
                        'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
                        'id'     => '[0-9]+',
                    ),

                ),
            ),
        ),
    ),

    'view_manager' => array(
        'template_path_stack' => array(
            'album' => __DIR__ . '/../view',
        ),
    ),
);

As we've registered an alias you can replace the controller option within the route defaults. You can thus use 'Album\Controller\Album' instead of the FQCN, but I rather use the FQCN within configurations. As it is easier to maintain your code.

One next thing you might bump into is that you are trying to use getServiceLocator() within your controller but this is no longer supported. Check this out: ZendFramework: ServiceManager - Factories
