Black Ice is AC/DC's fifteenth studio album since their 1975 debut and their first for eight years. Tipped to top the chart in several other countries, it bows empathically at number one here, with first week sales of 110,978 copies. It makes a much bigger impression than their last album, Stiff Upper Lip, which debuted and peaked at number 12 in 2000 on sales of 14,280 copies.
AC/DC has charted 14 albums prior to Black Ice but only one - 1980's Back In Black - got to number one. The gap of 28 years between number one albums is the longest of any act, eclipsing the 25 year hiatus between Elvis Presley's 40 Greatest Hits (1977) and Elv!s - 30 Number One Hits (2002).
The Bee Gees, Olivia Newton-John, Frank Ifield, Jimmy Barnes, John Farnham, Billy Thorpe, John Paul Young and Peter Andre are among a plethora of acts born in the UK but widely regarded as Australian.
80% of AC/DC fit that bill too - guitarists Angus Young and brother Malcolm originally hail from Glasgow, bassist Cliff Williams is from Romford, and lead singer Brian Johnson is from Gateshead. Only drummer Phil Rudd is a native Aussie. And they're pretty elderly for a number one group too - their average age is 56, three years younger than the record of 59 set by The Eagles last year.
The Kaiser Chiefs' third album, Off With Their Heads, debuts at number two on sales of 46,235 copies a fortnight after introductory single Never Miss A Beat peaked at number five.

With second single Don't Call This Love diving 3-11 on its second week in the chart, reigning X Factor champion Leon Jackson's debut album, Right Now, arrives at number four on sales of 37,197 copies.

German dance music phenomenon Sash! is back in the singles chart for the first time in eight years with Raindrops (Encore Une Fois) - a remake of his 1997 debut hit Encore Une Fois, now featuring Stunt.
