이단옆차기 (Duble Sidekick)

Duble Sidekick is a South Korean music producer and songwriting duo consisting of lyricist Park Jang Geun and composer Kim Jung Seung (also known as Chancellor (챈슬러) and formerly a member of One Way).

The duo was formed in 2010, and rose to fame after producing MBLAQ’s 2012 EP 100% Ver. Since then, they have produced many hit songs.

In late 2012, they expanded their team to include more composers and started their own entertainment agency called Duble Kick Entertainment.
