The name "BJ Shabalalala" is credited as the composer of all tracks on a Release Thandani by Ladysmith Black Mambazo. It may be that the name is a misspelling of Joseph Shabalala, the founder of the group. If this is correct, then a way to mark this would be to add an Advanced Relationship, Joseph Shabalala performs as BJ Shabalalala. Or, add BJ Shabalalala as an alias of Joseph Shabalala. At the moment, I don't think I have enough evidence to take either step.
