Direct access to album containing files having the same tag.

I think this is really a question that should be directed to your control point of choice, because you're ultimately asking for the ability to perform UPnP searches during browsing/playing, which can only be controlled by the control point.

I use BubbleUPnP and when browsing at the album level I'm given the options 'Albums by <AlbumArtist>' and 'Tracks by <AlbumArtist>', and when at the track level I'm given the options 'Albums by <Artist>' and 'Tracks by <Artist>', which is implemented with a UPnP search. I don't have any classical music so I have no way of telling if it'd offer other options like Conductor if it were populated.
