Lim Jeong-hyun

Lim played and recorded his cover of "Canon Rock" by JerryC on October 23, 2005.

Lim later stated to The New York Times that this had to do with the fact that "he recorded the audio and video independently and then matched them inexactly.

However his online fame has allowed him to play to live audiences several times— once for the South Korean ambassador in Washington, DC, then again at the KORUS festival the same year.

In October 2009, he was a featured performer at the fall ICANN meeting's welcoming ceremony and later joined in at their music night.

The beginning of the music video for Weezer's song "Pork and Beans" is set in Lim's iconic room, with the various members playing their various instruments.
