In March 2009, Midnight Oil performed "Blue Sky Mine" at the Sound Relief benefit concert in Melbourne, showcasing their significant revival as a band after their earlier disbandment in 2002. The song is from the album "Blue Sky Mining," released in 1990, which marked a critical period in the band's career as it addressed important social issues and helped solidify their political ethos in music. The performance at the Melbourne Cricket Ground was particularly meaningful, as it was part of a larger effort to raise funds for the victims of the Victorian bushfires and the Brisbane floods. Interestingly, "Blue Sky Mine" reflects the band's long-standing commitment to environmental and social justice, themes that have been prevalent throughout their work. The 2009 reunion highlighted not only their enduring impact on Australian music but also the band's ability to connect with fans through powerful live performances decades into their career.
