It's being reported that SISTAR's Hyorin has pulled out of KBS 2TV's 'Immortal Song 2' today due to scheduling conflicts. Her last recording for the competitive program will be on August 29th, and that episode will be broadcast on September 10th. Hyorin has received much praise for her singing prowess and her stage charisma during her involvement with 'Immortal Song 2'. Her husky, powerful voice has earned her the title of "Korea's Beyonce". A representative from MBC's popular competitive singing program, 'I Am a Singer', stated, "She's the idol singer I most want on the show. As someone who works for the television industry, you can't help but want this gem." Because 'I Am a Singer' is generally targeted towards veteran singers, it's all the more impressive that Hyorin was considered. SISTAR recently ranked 1st on Billboard's "K-pop Hot 100 Chart."
