Twenty-six albums by deceased artists have posthumously reached number one on the UK Albums Chart, a weekly record chart based on sales of albums in the United Kingdom. The first deceased artist to top the UK Albums Chart was Otis Redding, who died in a plane crash on 10 December 1967. On 20 May 1968, Redding's sixth studio album, The Dock of the Bay, was released in the UK – three weeks later, it became his first and only UK number-one album. Since Redding, 11 further artists have posthumously topped the albums chart, of which three have done so more than twice. The first of these was American singer Eva Cassidy; after dying in 1996, three posthumous releases from Cassidy reached number one in consecutive years, 2001–03. The second musician to achieve this feat was American entertainer Elvis Presley (pictured). The death of a musician can often result in an immediate increase in sales of their albums. Following his death in 2009, the number of purchases of Michael Jackson's albums grew significantly worldwide. In the UK, sales of the singer's albums increased by more than 80 times in a single day.
