AC/DC are an Australian rock band, formed in 1973 by brothers Malcolm and Angus Young. The band is commonly classified as hard rock and are considered pioneers of heavy metal, though they themselves have always classified their music as simply "rock and roll".
Malcolm and Angus Young developed the idea for the band's name after their older sister, Margaret Young, saw the initials "AC/DC" on a vacuum cleaner. "AC/DC" is an abbreviation meaning "alternating current/direct current" electricity. The brothers felt that this name symbolised the band's raw energy, power-driven performances, and a love for their music. "AC/DC" is pronounced one letter at a time, though the band are popularly known as "Acca Dacca" in Australia.
Black Ice World Tour was a 2008/2009/2010 concert tour by Australian rock band AC/DC in support of the group's 15th studio album, Black Ice, which was released in October 2008. The tour was the band's first since the Stiff Upper Lip World Tour in 2000/2001.
The tour ended up being the most successful by AC/DC, grossing roughly $441.1 million, making it the third highest-grossing concert tour of all-time. By the tour's culmination, the group had played over 160 shows to approximately 4.9 million people. The tour was one of the highest grossing concert tours in history, grossing$441.6 million, third behind The Rolling Stones' A Bigger Bang Tour, which grossed $558.3 million in the mid-2000s, and U2's 360° Tour, which has a current gross of $443.1 million.
The jaunt began in Wilkes-Barre, Pennsylvania, United States in late October 2008. By spring 2010, the tour had reached North America, Europe, South America, Oceania and Asia. AC/Dc played the 16th of May 2010 in Bucharest - Piata Constitutiei, in front of 60,000 people, one of the biggest gigs ever done in Romania.
