"Then and Now" is a new series which takes an in-depth look at the transformation of K-pop's trendiest artists--how have they changed since their debut? Certain connoisseurs prefer Vintage rather than new, you fell in love with the original but as time goes by, things change and so do artists. While others like the evolving and growth of artists experimenting with new things. Have they changed for the better or do you prefer the old school flavor? �Read on and cast your own vote to find out!

For the inaugural edition of "Then and Now," I thought it would be fitting to cover one of the hottest (if not the hottest) K-pop groups at the moment: (say it with me: B-B-B-BIG BANG!)�

Then

Big Bang's debut in 2006 was not as explosive as their name would suggest--it was a rumble rather than a bang. �Looking back, however, it is undeniable that the same charm and charismatic stage presence that has since led the group to global stardom were present from the start. �Now, lets take a look at the music video for "La La La," one of Big Bang's first singles:�

Vintage Big Bang is like an awesome mash-up of 1TYM�(another old school YG group) mixed with Backstreet Boys, if that's even possible --anyone else see or hear what I'm talking about?. �Their sound has a classic 90s to the early 00s hip-hop and R&B vibe--"La La La" is an easy song to listen to with a simple, yet catchy, backtrack beat and smooth vocals. �The music video is light, consisting of synchronized dancing and the classic oversized layered tees, baggy jeans, and bandanas (and let's not forget the fresh all-white look), that we saw on American hip-hop artists in that era, and of course YG's OG group, 1TYM. �By 2013, however, Big Bang evolved into a much different, sophisticated group of artists.�

Now

In Big Bang's recent music video for their single, "Monster," we see a huge shift in both image and sound. The video is visually appealing--and not solely due to a significant increase in production value, nor because sometime between 2006 and 2013, Big Bang evidently collectively hit the gym. �Rather, it is clear that the members have found their individuality. �From the lyrics to the video concept, there is a deeper meaning concealed for the viewer to decode, and the image of each member is expressive art in itself.�

I believe Big Bang as a group is, naturally, artistically stronger today--they have found a unique sound, and the members have learned to incorporate their own style and emotions into everything from their lyrics to their fashion. �Despite this fact, however, I will always have a soft spot for old-school hip-hop and R&B--my favorite playlist on my iTunes is titled, "slow jams."--and thus, I absolutely love and potentially prefer, the sound of vintage Big Bang.
