In March 2009, Midnight Oil reunited to perform "One Country" during the Sound Relief benefit concert held at the Melbourne Cricket Ground. This performance came nearly a decade after their last studio album, "Capricornia" (released in 2002), marking a significant moment in their career as they showcased their enduring relevance and commitment to social issues. "One Country," originally featured on the 1990 album "Blue Sky Mining," reflects the band's ecological and political themes, which have been central to their identity. The Sound Relief concert was organized to support victims of the Australian bushfires and floods, revealing Midnight Oil's dedication to humanitarian causes. This performance not only serves as a nostalgic reunion for fans but also highlights the band's historical role as advocates for environmental and social justice issues, maintaining their legacy while engaging in contemporary crises.
