Madonna Louise Ciccone Ritchie performed as a member of the pop group Breakfast Club and she managed to release her self-titled debut album in 1983. After that she produced three number-one studio albums in the 1980s.

Sticky and Sweet Tour is the seventh world tour concert of the American pop singer and it supports her eleventh studio album, Hard Candy. The tour will come to Europe, North America and South America and it will be her first tour since she started recording with Live Nation, after the Hard Candy Promo Tour.

The tour’s program is described as a “rock driven dancetastic journey” and it will be performed in four acts, including pimp, which is a fusion of modern urban life in the 1920s, old school which will represent Madonna visiting her early days in New York, gypsy that will represent a blend of nomad gypsy culture and folk music and rave which is a futuristic dance floor.

The pop American singer turned 50 this month and started her world tour on Saturday night at Millennium Stadium in Wales. Reports showed that the concert began with political issues when Madonna was singing “Like a Prayer” as images of Hitler and Robert Mugabe were followed by ones of Senator John McCain. Another video interlude also showed Barack Obama but together with Gandhi, John Lennon and Al Gore.

"The comparisons are outrageous, unacceptable and crudely divisive all at the same time. It clearly shows that when it comes to supporting Barack Obama, his fellow worldwide celebrities refuse to consider any smear or attack off-limits," McCain’s spokesman, Tucker Bounds, said in a statement.
