The players are Jun Roh (Guitar/Vocals), John Ahn (Bass), Jincheol Kim (Drums) and session synth player Young Kwang Joung.
They sing in English so would translate all around the world and surely be a hit in the USA with their American clothing style and catchy Daft Punk electro and 8's guitar riffs, and that's just part of the unique sound they bring. Only 2 E.P.'s have been released as far as I know so far and they are quite an introduction.
A song entitled "Down Below" appears on Asian soundtrack albums, which is a softer vocal song but still contains the guitar riffs, the catchy chorus and the synth 80s Electro background.
