Rain has been popular for his singing and dancing talents since he was a teenager. As a young teen, Rain fell in love with dancing. In order to make his dream of becoming a singer come true, Rain joined a dance music group named “Fan Club.”
The dance group was made up of 6 male members who attempted to enter the local pop music market with the song “In Search of Dreams,” a re-made version of Chumbawamba’s hit song “Tubthumping.” Although the band gained some interest, they didn’t create the sensation they had hoped for. After releasing its 2nd album in 1999, Fan Club decided to disband.
After the band broke up, Rain was scouted by noted producer and entertainer Park Jin-young and had another chance to make it in the local entertainment industry. Park Jin-young believed that Rain’s vocal ability and dance moves were sophisticated and strong and decided to train him to become a top star in the local pop music world.
Rain’s first solo album got a great response. Since then, every album Rain has released has been successful. In addition to music, Rain has acted in several TV series.
After wrapping up his Madison Square Garden concert back in February 2006, Rain had the choice of putting an English album together and jumping head-first into the U.S. market or heading back to Asia to cement his popularity with a world tour first. He went with the latter because he felt that the first order of business was giving thanks and attention to those in Asia, where his current fan-base is. Towards the end of 2007, Rain will officially release a much-anticipated English album.
