Standard for tagging music files with artist's 'aliases'? Options

[SoberWarlock]

What is the universal tag that identifies the artist's aliases so you can have a better search result for a well documented library of songs.

For Example:

Twista was known as "Tung Twista" in his early releases as a rap artist, but for every release I want to add an alias so I can remember that it is the same artist and I don't have to make more folders when I can put his discography in one folder labeled as "Twista".

Just one more data point, but I do what BoraBora does, however using the ALBUM ARTIST tag rather than his custom tag (which echoes what slks wrote).

But at the end of the day, do what works best for you.
