In November 2011 Landon uploaded a video to his YouTube account encouraging fans to donate to the cause. With a donation of twenty dollars or more to his music blog donation page, he entered users into a raffle. The three people that were chosen were contacted and asked their favorite song by Landon. Those three people got a personalized YouTube video of Landon thanking them for their donation with a special performance of their chosen song. David and Luca chose "Falling in Love at a Coffee Shop," Paige chose "Take a Chance," and Karen chose "Little Darlin'." He was able to help contribute to the overall musician's donation count of 600,000 dollars. In addition to his fundraising competition, he played at the Nashville, Tennessee location on the "Break the Silence" tour for Invisible Children. It was held at Lipscomb University on Monday, April 25, 2011.
After his song "This Is The Way It Ends" was featured on the 6th-season finale of television-drama series Grey's Anatomy and subsequently went into national rotation, Pigg began a publicity tour in summer 2006 which found him booked on Late Night with Conan O'Brien, Last Call with Carson Daly television talk shows and other media outlets including a radio tour, as well as appearances in Teen Vogue, Glamour and Performing Songwriter magazines. In late August, Pigg appeared on the television program The Early Show where he played "Can't Let Go", the first track from his album, LP (2006).

The last full tour Landon went on was for his last album, The Boy Who Never, and it went from March 2010 until June 2010. He toured with Madi Diaz, and the tour went through 15 states with 23 different venues. Since the tour in 2010, Landon opened for Lissie at Webster Hall, played on the Invisible Children "Break the Silence" tour, and had concerts at Loyola Marymount University and Knox College in 2011.

Pigg has been active on his YouTube account. One posting was promoting The Perks of Being a Wallflower. He also posted an in-the-making video of "Little Darlin'". Before that he had several videos of his pets, and played two unreleased songs acoustically. "Young at Heart" was played on Halloween and "The Foggiest" was uploaded in 2012. Along with those he did a series of acoustic renditions of his songs called, "Backyard Sessions". Each of these songs were played in his backyard, or in nature. On another YouTube account, his road band members that tour with him created a few acoustic videos for some songs from The Boy Who Never. These songs include, "A Ghost", "Take a Chance", and "Falling in Love at a Coffee Shop".” Several photos were posted on his Facebook account during this time, and he also tweeted numerous times. Landon was mostly silent on social media in 2013. Fans tweeted and posted to his Facebook asking if he would release new music in the future. It is still unclear if Landon was quietly working on new material at the time or if he was on hiatus. On July 1, 2014, Landon posted a photo of himself in a recording studio to his Facebook page, captioned, "Recording Today." In November 2014, Landon and William Close released a cover of Joni Mitchell's song, "River," on iTunes. As of November 2014, no plans for a new album or tour have been announced yet.
