Both Paparizou and Panagiotidis were born and raised in Sweden by Greek parents. Their debut single "Opa Opa" became a hit amongst the Greeks in Sweden and eventually entered the top ten in Sweden and Norway, making them the first act to enter the Swedish top five with a song sung in Greek. They were also the first ever to be nominated for a Swedish Grammis Award in the category Modern Dance with a Greek song. In 2001, Antique was selected to represent Greece at the Eurovision Song Contest in Copenhagen with the song "Die For You", sung in a blend of English and Greek, ending with a third place.
Paparizou admitted that Greek music had been something of an acquired taste for her, and that the name "Antique" was probably a reflection of her childhood impression of it being something rather distant and old-fashioned; something that she only really associated with her summer holidays in Greece.
Antique disbanded in late 2003 on good terms with both members pursuing solo careers. Paparizou and Panagiotidis have expressed to want to reunite in the future.
