I would like an artist to artist relationship for cases where a group changes name and now performs under a different name.

The forward relationship would be: now performs as
The backward relationship would be: previously performed under the name
A date on this relationship would indicate when the name changed.

For example, The Chemical Brothers once performed under the name The Dust Brothers but had to change thair name.
