One artist with two roles

Whether one party plays two roles or two parties playing one role each makes a big difference: The “one party” samples show one person, John Smith, who played two roles, soloist and producer, during the creation of a sound recording or video. The “two party” samples show two different people, unfortunately both called John Smith, each of which plays one role each. To avoid this confusion, it is recommended to always add a Party ID to any composite describing parties.
