This is going to sound like a plug, but CGI::FormBuilder supports a 
"growable" option for fields that automatically gives you client side JS 
hooks to do this. You get a button that would say something like 
"Additional Artist" which would append to the DOM more fields of a given 
type on the fly. These inherit any field validation you have specified 
as well (both server and client validation is generated).

FormBuilder is on CPAN and there's a plugin (which may become a 
controller class later) for Catalyst as well. It slots right into the TT
