Fresh off her successful performance at the Super Bowl Halftime Show, Madonna has several upcoming stops on her world concert tour among the onsales for the weekend ending February 13 as compiled by TicketNews.

One of the most popular recording artists of the last 30 years, Madonna has sold over 300 million albums worldwide throughout her storied career. Her 12th studio album, titled "MDNA" will be released this year, accompanied by a world tour -- her first in roughly three years.

After taking a couple years to tour nationally and internationally, Elton John will return to Las Vegas later this year for his second headlining residency at the Colosseum at Caesars Palace.

The show, entitled "The Million Dollar Piano," is booked into a three-year block at the same venue that housed his earlier "Red Piano" run. Dates and onsales have been revealed for the first 16 nights of the residency, which opens September 28 and continues with performances on September 30, October 1-2, 6-9, 13-15, 18-19 and 21-23.

Elton John has expanded his plans winter and spring tour plans for North America. The rock musician will hit arenas and conventions centers across the continent over nearly three months.

The 20-city trek launches early next week with a February 14-15 stand at the Save-on-Foods Memorial Centre in Victoria, BC. And thanks to the recent unveiling of more dates, John's concert calendar now stretches through a May 6 performance at the Entertainment Covention Center in Duluth, MN.

Elton John and Leon Russell have once again expanded their plans for the co-headlining Union Tour, which promotes their upcoming T Bone Burnett-produced album "The Union."

As previously announced, The Union Tour launches on October 19, the album's official release date, with a concert at Beacon Theatre in New York, NY. But with the recent addition of four more concert dates, the stateside run now extends through a November 21 event at the Lakeland Center in Lakeland, FL.

Piano-playing icons Elton John and Leon Russell will debut their new collaboration in concert several weeks earlier than previously expected. The veteran musicians this week announced plans to play for New York City audiences on the release date for their upcoming album, "The Union."

The record release and coinciding concert are scheduled for October 19. John and Russell will take the stage at the historic Beacon Theatre in New York, NY, performing a mix of songs from their new project, as well as selections from their respective careers.
