Add a SkinScript method to your Specialist, under the Data-PlugIns tab, 
with something like this:

WITH self.propertysheets.get('cd_info') COMPUTE
artist=getProperty('artist'),
label=getProperty('label')

You can then write your ZClass index_html and use <dtml-var artist> or 
&dtml-artist; where you want the artist, and similarly with label.
