Nope, I'm not talking about the TV show, or the scientific theory; I'm talking about the Korean band Big Bang.
I will list the members of Big Bang by oldest to youngest, stage name first, then real name in an English name order. In Korea it would be last name first.
TOP, Seung Hyun Choi--songwriter, rapper, actor and model
Gdragon, also goes by GD— Ji yong Kwon—the leader of Big Bang, songwriter, singer/rapper
Taeyang, Young Bae Dong— singer, dancer
Daesung, Dae Sung Kang--singer, actor
Victory, Seung Hyun Lee –singer, actor, host
I am including Wikipedia’s excerpt about Big Bang too, since it has a lot of great information.
Big Bang or Bigbang (Korean: 빅뱅; stylized as BIGBANG) is a South Korean male group under the management of YG Entertainment. Formed in 2006, the group consists of G-Dragon, T.O.P, Taeyang, Daesung, and Seungri. Big Bang is known for their unique urban-originated music and fashion style. The members' involvement in composing and producing their own music, most notably leader G-Dragon, has earned the group respect and praise from music industry experts.
The group's turning point came with their hit song Lies, which stayed at number one on Korean charts for a record-breaking seven consecutive weeks. Their follow up releases, Hot Issue and Stand Up, furthered their success, spawning hits such as Last Farewell and Haru Haru. From 2007 to 2008, Big Bang received many awards, including "Best Male Group", "Song of the Year", "Artist of the Year", and the Grand Award at the Seoul Music Awards.
From 2009 to 2010, Big Bang expanded their endeavors to Japan, and were voted "the Korean group that Japanese fans wish to see the most". They became the first foreign group awarded "Best Newcomer" from the Japan Cable Broadcasting Station and "Best New Artist" at MTV Japan. Amidst their Japanese group promotions, the members branched out to do solo activities. Taeyang, G-Dragon, and Seungri have released solo albums. G-Dragon and T.O.P also collaborated on an album under the sub-unit GD & TOP. Seungri and Daesung have acted in both TV dramas and musicals. T.O.P became a highly acclaimed film star. Daesung also hosted many of Korea's most popular variety TV shows.
After nearly a two-year hiatus in Korea, Big Bang reunited in 2011 with their successful album Tonight. However, promotions were cut short when multiple members encountered legal issues. In November 2011, representing the Asia-Pacific region, Big Bang emerged as the inaugural "Best Worldwide Act" winner at the 2011 MTV Europe Music Awards. This was the first time in six months all five members were seen together. In 2012, Big Bang released their fifth Mini Album Alive in Korea and Japan before embarking on their first ever World Tour which concluded in early 2013.
I was lucky enough to go to their sold out Alive concert at the Honda Center in Anaheim, and I can easily say I have never seen a band give so much on stage. The concert went on for at least three hours and they practically crawled off in exhaustion. Even though they are internationally popular they still have such a great appreciation of their fans. Their music is addictive and with their constant evolution you are kept continually enthralled. The bonds between the members will charm you, their variety show appearances will make you laugh, and their music will make you dance. Obviously I can’t hide how fangirl I am when it comes to Big Bang. I hope you enjoy their music as much as I do.
