In the artwork view when you right click an artist then 'Play More> Play All Tracks Shuffled' this should play all tracks shuffled by said artist rather than the whole library. Please correct me as I'm probably wrong but the only way I've found to do this is to create an auto playlist for an artist. Either way I still think the right-click option is far more logical and I still think is a good idea.
