The talented but very underrated ladies of Big Mama recently released the music video for ???? ?? Going Crazy Waiting, the title track from their newly released album titled 5. Big Mama consists of Shin Yeon Ah, Lee Young Hyun, Lee Ji Young, and Park Min Hye. M Boat / YG Entertainment formed Big Mama back in 2003 solely on their vocal talents (didn't care about their looks or body). Their first single Break Away demonstrated this by the music video showing four beautiful women lip synching on stage to Big Mama's vocals. This first album sold over 100,000 copies, the girls had some success and moved away from M Boat / YG Entertainment in 2007. Since then they've participated in various solo activites and features but now they've finally banded together to create this new album. Thanks to Kang Mi for the tip and check out the MV below.
