NRG's second album "Race" was released that same year, and featured more high energy dance songs like "Messenger", selling over 300,000 copies in South Korea. With the second album, NRG was also able to find success outside of Korea, selling albums in both China and Japan. NRG became the first South Korean musical group to actively market themselves in China, where they have sold over 100,000 copies. Today, NRG is widely credited as one of the pioneers of the Korean Wave (Korean Hallyu) that first swept through Asia in the late 1990s.
