[mb-users] Group had to change there name - two artist entries?

[Alexander Kiel]

Hi List,

please look at the group nimmzwei [1]. They had to change there name in 
2002/2003 to superzwei because nimmzwei is a product name of the German 
candy nimm2 [2]. You can read about the name history [3] if you be able 
to read German.

If you look at there Covers [4] they used the name nimmzwei until "Intim 
2000" and began to use superzwei with "superzwei live".

So am I right if I opt for removing the superzwei alias on nimmzwei and 
create a new superzwei artist instead? What would be the appropriate 
relationship between the two Performance Names than?

Regards
Alex
