Na-ul, a member of South Korea's popular R&B vocal band Brown Eyed Soul, will make his first comeback in five years in November.
"Na-ul is preparing for his official album," the 39-year-old's agency Santa Music said in a statement on Thursday, adding the singer is in discussion over how he would release the new album. "Na-ul could release a single album before the actual release of the EP or split the album into two mini-albums."
Na-ul gained fame as a skillful singer as a member of an R&B duo group Brown Eyes. He later formed Brown Eyed Soul, a soul quartet in 2003.
