The story begins with rock singers Yoon Do Hyun and Ha Hyun Woo, who teamed up with tvN for a special bromance travel variety called 'Rock Bros'. The premise of 'Rock Bros' is that the two rock singers embark on a road trip to Ithaca, Greece. The catch? Their entire trip, which began in Ankara, Turkey, will be funded by netizens via SNS.

The two singers of 'Rock Bros' upload live performance clips on both YouTube and Facebook from their current destination throughout their road trip, and the views of both SNS platforms combined are the source of their trip's funding. It seems that as of April 17, F.T. Island's Hongki has joined in on the road trip in order to perform a duet with Ha Hyun Woo of "Red Feld" (originally by Guckkasten) featuring Yoon Do Hyun on the tambourine. 

Earlier, 'Rock Bros' revealed that the three travelers were rewarded with enough money to buy a meal - famous Hungarian kebobs - through viewers' SNS support. 

Very soon, viewers will be able to catch the 20-day journey of 'Rock Bros' on tvN as a variety series, but until then, keep an eye out for more scenic live clips on YouTube and Facebook!
