Later that year, m-pact was one of four groups selected to perform in an international a cappella festival / concert called "Amazing Voice", which took place in August 2007 in South Korea. The other participating groups were The Real Group (Sweden), Rajaton (Finland), and The Idea of North (Australia). The groups performed 2 preview concerts at Phoenix Park in Gangwon-do, South Korea prior to their 2-night sold-out run at the Sejong Performing Arts Center in Seoul. The festival was such a huge success that it was immediately re-booked for a 2nd run in August 2008.
