Hey folks, I have imported the following (using -A and the existing tags):

How can I reset the albumartist and move these into a single directory?

The best way is probably to remove these from your library database (beet rm) and then import them again as a single album (perhaps with beet import --flat to ignore the existing directory hierarchy).
