Tickets for the upcoming 2011 Major League Baseball season, as well as tickets to several upcoming concert dates from Keith Urban are on sale throughout the weekend ending March 7 as compiled by TicketNews.

Starting off this weekend's onsales are tickets to four Major League Baseball teams' 2011 home seasons. First up are single game tickets for the St. Louis Cardinals. Perennial contenders for first place in the National League Central division, Cardinals tickets go on sale today. Among Saturdays onsales are tickets for both the Detroit Tigers and the Washington Nationals.

Australian country musician Keith Urban has a new album under his belt and a fresh headlining tour set for 2011. The Get Closer World Tour launches its North American leg June 16 at the Civic Center in Mobile, AL.

Forty-four dates are booked across the United States through the summer. Urban's calendar currently closes with an October 15 event at the Target Center in Minneapolis, MN.

Two of country music's hottest acts, Keith Urban and Taylor Swift, find themselves and their representatives at the center of a growing ticketing controversy in Nashville, as news of the extraordinary number of tickets that are held back and distributed to fan clubs and other parties comes to light.

In both cases, thousands of tickets were reallocated to American Express and the artists' fan clubs for separate concerts in the city in recent weeks, according to a scathing report on the issue by WTVF-TV News Channel 5 in Nashville. The sheer number of holdbacks, many of them premium seats that then made their way to Ticketmaster Entertainment's ticket resale site TicketsNow, ultimately meant that only a fraction of tickets were made available to the public, but fans were never told that the odds of them scoring tickets to the shows were dramatically reduced.

Updates and announcements from the likes of KISS and Incubus are in the stars for the May 28 daily tour recap, as compiled by TicketNews.

To start, KISS will get support from Buckcherry on the band's long-awaited North American tour. Fans can still vote to bring the tour through their hometown, though Canadian cities are currently leading in the polls over U.S. destinations. Alternative rock group Incubus also has a special offer for its fans. The group has announced the auction of premium tickets on eBay, and all proceeds will benefit the band-founded Make Yourself Foundation.

Before launching his arena-sized summer tour, country star Keith Urban has announced a block of "No Frills" performances that will take him through the nation's clubs and theaters. The six-show run begins March 18 at the House of Blues in Dallas, TX, and wraps April 3 at the Theatre of the Living Arts in Philadelphia, PA.

Other stops are set for March 24 at The Fillmore in San Francisco, CA; March 27 at the House of Blues in West Hollywood, CA; March 30 at Joe's Sports Bar in Chicago, IL; and April 1 at Webster Hall in New York, NY.
