Today the artists VIBE, 4Men and Lee Younghyun met in a Seoul studio to rehearse for their concert "Crazy Soul" (subtitled "Don't Go Mad"). As implied by the title, the concert showcases the best soul singers of South Korea. The three soul artists go head-to-head in this event. 

Walking through the studio this day, one could hear Lee Younghyun warming up his vocals to "Mermaid." A little further down the hall, one's ears would have rejoiced at hearing the deep soulful voices of the groups VIBE and 4Men rehearsing songs "The Woman in the Light," "Sparks" and "Promise U."

In a question and answer session, the artists promised "a concert that won't be limited to ballads" and "a completely new image for the artists, a concert where viewers will dance along and we guarantee 200% that they will enjoy themselves. Furthermore, it will be have elements of a parody and be similar to some of the other music shows."

The "Crazy Soul" concert will take place on December 29-31 at Kyunghee University's Hall of Peace in Seoul.
