Cyndi Lauper, an American pop star of the 1980s, has canceled her planned concerts in South Korea to mark the 30th anniversary of her debut solo album, a local organizer said Sunday.

Lauper planned to hold two concerts at Seoul’s Olympic Park on Jan. 23-24 as part of the “She’s So Unusual: 30th Anniversary Tour” that began in June 2013 and has taken her to 56 cities around the world.

“The decision has been made in consultation with the artist,”YESCOM Entertainment said, without giving a specific reason.

Industry watchers said lackluster ticket sales may be responsible for the cancellation.

The 61-year-old pop star held her first concert in South Korea in 1989.

Lauper surged to stardom in 1983 with her debut album that sold 30 million copies worldwide. She has established herself as a pop icon, winning awards at the Grammys, Emmys, Tony Awards, MTV Video Music Awards, Billboard Music Awards and American Music Awards.

In 2014, Lauper was awarded the Grammy for best theater musical album for the Broadway musical “Kinky Boots,” which she composed and wrote the music for. (Yonhap)
