On April 7th, Brave Girls finally made their debut with their first single, "the Difference"! Prior to their debut, the girls headlined countless amount of times for not only being produced by Brave Brothers (the man behind the success of Big Bang, Son Dambi, After School, and SISTAR), but for the members' individual experience in music, dance, and visuals. Their first single includes their title track, "Do You Know," along with their second title track, "So Sexy". Though everyone expected them to shoulder Brave Brothers' synthetic sound, "Do You Know" is actually a slow-tempo R&B track with a gospel style arrangement. Check it out below!
