Carrie Underwood and Luke Bryan are among the first artists to be confirmed for the 2013 CMA Fest, which is set to invade the streets of downtown Nashville on June 6-9.

Underwood's inclusion in this year's event is no surprise considering the 'Two Black Cadillacs' singer has been present for each CMA Fest since bursting onto the scene in 2005. In fact, the former 'American Idol' winner used the stage as her very first appearance following her win on the popular reality competition series.

Bryan has also become quite the fan favorite in recent years. The country superstar's career is red-hot right now, with a handful of No. 1 singles to his name and nearly 10 million album and singles sold. Given his recent unprecedented sweep during the ACA Awards, Bryan is expected to be a huge draw during this year's CMA Fest.

Lady Antebellum and Little Big Town have also been confirmed for the event. Given the CMA Fest's reputation as the ultimate country music experience, a slew of the genre's biggest names are expected to be confirmed for the four-day extravaganza in the coming weeks.

Tickets can be purchased through Ticketmaster at Ticketmaster.com. They are also available by calling 1-800-CMA-FEST (262-3378). Ticket prices range from $125 to $350 (plus handling fees) and are based on the level of seating at LP Field for the nightly concerts.
