Seoulsonic (SEOULSONIC), (Korean: 서울소닉) is an annual concert tour in the United States and Canada, organized by the DFSB Kollective with support from the Korea Creative Content Agency (KOCCA), which began in 2011 in an effort to introduce South Korea's indie music culture to the West.

[1][2] The tour includes annual stops at SXSW in Austin, Texas and the Canadian Music Week in Toronto, Canada.

The tour started in 2011, at which time the music scene was described as follows: "the rock genre is still the obscure cousin of pop, dance and hip-hop, and other revenue streams such as product endorsements and television appearances aren’t readily available to its musicians.

As cool as flashy K-pop may be, the cold hard facts and figures tell us the American music market is marching to different beats.

[6] The 2K11 "Seoulsonic North American Tour" started on March 9, 2011 at the Canadian Music Week in Toronto, Canada, and held other shows,[9] including the Knitting Factory in New York City and the Roxy in West Hollywood, California.
