Pop-rock singer-songwriters Gavin DeGraw and Colbie Caillat have announced plans to team up later this year for a tour that will take the pair around the eastern and Midwestern portions of the United States.

The 22-date tour will kick off on May 25 at the Charter Amphitheatre at Heritage Park in Simpsonville, S.C. and will continue through June 29 when the tour concludes with a show in Highland Park, Ill. at the Ravinia Festival.

Other cities the tour will visit include Biloxi, Miss.; Philadelphia; Charlotte, N.C.; Bee Cave, Texas; Sioux City, Iowa and Apple Valley, Minn. Andy Grammar will serve as the opener for the dates.

In other DeGraw news, he began a stint on the 14^th season of ABC’s “Dancing With the Stars” reality show this past Monday. The singer’s latest CD, Sweeter, was released in September of last year and debuted at number eight on the Billboard 200 albums chart. The record has since gone on to sell 129,000 copies and recently scored DeGraw his first number one song on the Adult Pop Songs chart with “Not Over You.” The album is DeGraw’s fourth studio album.

Caillat’s most recent album, All of You is her third studio album and was released last May. The album debuted at number six on the Billboard 200 and has since sold 256,000 copies. Her current single is “Favorite Song” and features hip-hop artist Common.

Caillat first burst onto the music scene with her debut album Coco in 2007. That album has gone on to be certified 2x platinum in the United States, selling over 2 million copies. She won two Grammy Awards at the 2010 ceremony. One was for Best Pop Collaboration with Vocals for “Lucky,” her duet with Jason Mraz. The other was as a featured artist on Fearless, the Taylor Swift record that won the Album of the Year award.

Colbie Caillat, the chart-topping and Grammy award-winning singer-songwriter from Southern California, will be hitting the road starting on August 24 to support “All Of You,” her critically acclaimed third album. Last week, the set debuted in the No. 6 spot on Billboard and No.2 on iTunes. The tour will kick off at Brown Theatre in Louisville and include 27 U.S. college towns and major markets. Andy Grammer is opening all of the shows except three on the tour.

She kicked her new album off by performing “Brighter Than the Sun,” her current single she and Ryan Tedder co-wrote on EXTRA, Fox’s Daily Dish, the Tonight Show and the Today Show. On August 1 she will be appearing on Lopez Tonight. Both Entertainment Weekly and People Magazine chose “Brighter Than the Sun” as one of their single choices, with Entertainment Weekly raving that the song was full of beach ready romance and carefree acoustic strums. “I Do,” the new album’s first single debuted in the No. 1 spot on iTunes, in Europe is getting Top 5 airplay, and on the Hot AC single chart is in the Top 15.

“All Of You” has received critical raves from USA Today, Entertainment Weekly and People Magazine, among others. USA Today called it the best album from Caillat to date, while People Magazine described it as the summer’s sunniest set. Caillat was able to realize a long standing dream of hers when she collaborated with Common, the film star and rapper, on the album. He contributed his rhymes to “Favorite Song.” Ryan Tedder and Caillat co-wrote “Brighter than the Sun” and “Favorite Song” and collaborated with Justin Young, Rick Nowels, Jason Reeves and Toby Gad on the album.

“Coco,” Caillat’s first album, debuted in the No. 5 spot and broke through the multi-Platinum barrier. “Bubbly,” her first single, has turned out to be one of the all-time top-selling digital tracks. Billboard named Caillat as their Breakthrough Artist of the Year. “Breakthrough,” fittingly, debuted in the No. 1 spot. Caillat later that year received four Grammy nominations, winning two for collaborations with Taylor Swift and Jason Mraz. She performed in Oslo for the Nobel Peace Concert and sang the national anthem to kick the NFL’s 2011 season off. Caillat has also been a spokesperson and been involved with several charitable organizations, including the Humane Society, Farm Sanctuary, Save the Music and Surfrider Foundation.

The second studio album of the blue eyed singer Colbie Caillat, “Breakthrough,” is definitely living up to the name. The up-and-coming singer is anticipating a No. 1 debut next week on Billboard’s 200. She is also in the middle of preparing for a new upcoming headlining tour.

Caillat’s North American leg of her “Breakthrough World tour” will kick off in San Diego, CA at House of Blues on September 15. The 30 city circuit will close out in West Hollywood, CA at House of Blues October 27-28. Howie Day, songwriter and singer, will be providing supporting on Caillat’s North American leg.

Some highlights from the fall portion of the tour include performances at House of Blues on September 16-17 in Anaheim, CA; at McMenamins Crystal Ballroom on September 30 in Portland, OR; at Riviera Theatre on October 7 in Chicago, IL; at Roseland Ballroom on October 16 in New York, NY; and at Rialto Theatre on October 26 in Tucson, AZ.

Caillat’s 2009 itinerary will also include three concerts held in Canada. She will be at Commodore Ballroom on September 29 in Vancouver, BC; at Kool Haus on October 10 in Toronto, ON; and at Metropolis on October 11 in Montreal, QC.

The California native singer’s second album, “Breakthrough,” had a US release date of August 25 and was released a few days earlier in some of the international markets. A No. 1 debut is being projected by Billboard and sales are estimated at 90,000-100,000 units.

The debut album of Caillat’s, “Coco,” set a very high precedent. Since it was released July 2007, the album has gone onto to become certified double Platinum, with sales of around three million worldwide copies.

Caillat, in describing her songwriting process at her website said, if something is biting me, then I hold it in. That’s the type of person that I am. It all comes out in my songs. Things build up inside. Then I will end up writing three songs in one weekend. It is a release for me. It is just there. I don’t really choose what I want to write about.
