The concerts, consisting of traditional Lucia and Christmas songs, are considered to be the largest Lucia concert in the world, according to the Guinness Book of World Records.
The choir is comprised of approximately 1,200 children and young people from Adolf Fredrik's Music Classes and Kungsholm's Music Gymnasiet, and is accompanied by the Stockholm Philharmonic Wind Orchestra.
This year more then 9,000 people attended each of the concerts, held the weekend prior to Lucia Day, December 13th.
But not all tickets were sold to proud family members and friends of the choir.
“I try to attend the concert each year," said attendee Ann-Christin Nilsson.
"It is always a treat at this time of the year”.
Choir leader Kris Grayborn, has travelled from Östersund in northern Sweden for the third year in a row to listen to the concert.
“I appreciate good music and this concert is the best we can hear of young people in Sweden today. It is of the highest calibre and with so many voices, it is just fantastic,” she said.
