For the past 25 years, Farm Aid has held almost annual concerts across the United States in an effort to raise funds and awareness for the nation's family farmers. To celebrate this year's anniversary milestone, the event will take place at a ballpark for the first time in its lengthy history.

Farm Aid 25: Growing Hope for America, scheduled for October 2 at Miller Park in Milwaukee, WI, was announced today in a press conference with event co-founders Willie Nelson and John Mellencamp.

Cultural icon and musician Willie Nelson is known for his nearly non-stop touring, and he'll continue that standard in the early months of 2010 with another leg of tour dates.

At the moment, the 76-year-old road dog's early year calendar is focused on markets in the central and south United States. The 30-city itinerary launches early in the New Year with a January 7 concert at Abraham Chavez Theatre in El Paso, TX, and continues through a March 17 gig at the annual Country Thunder USA music festival in Florence, AZ.

Tickets for upcoming concerts from Mariah Carey as well as tickets for the upcoming shows from Willie Nelson are on sale throughout the weekend ending September 7 as compiled by TicketNews.

This weekend's onsales begins with tickets to check out rockers Snow Patrol in concert. On sale today, the band will be performing in concert in Los Angeles. Going on sale this morning are tickets to see two country stars in concert. Country legend Willie Nelson has shows in South Carolina and Louisiana on sale this morning, while country diva Martina McBride has concerts in Mississippi on sale today. Continuing with the Friday onsales are tickets for upcoming concerts from rapper Mos Def in Baltimore as well as tickets to see R&B star Jamie Foxx in concert in Seattle and Fresno.

Much like baseball, attending concerts by legendary singer-songwriter Bob Dylan could very well be considered an American pastime. This season, the two will be combined on the Bob Dylan Show's 2009 Ballpark Tour.

Dylan's 22-city tour will weave a coast-to-coast path, stopping in minor league baseball parks across the nation. The trek begins July 2 at GCS Ballpark in Sauget, IL, and closes August 15 at Banner Island Ballpark in Stockton, CA.

Country outlaw and prolific touring musician Willie Nelson has postponed three concerts in Florida due to illness, which was not specified.

The three shows -- March 17 at Ruth Eckerd Hall in Clearwater, March 18 at the King Center for the Performing Arts in Melbourne and March 19 at the Marina Civic Center in Panama -- have been rescheduled for October. However, no specific dates have been set for the postponed performances.
