Reunion, Full Circle and 2012 tour (2009–2012)
While Tremonti referred to Creed as "officially in our past" in 2006, in April 2009, Creed's website announced that the band had reunited for a new tour and plans for a new album. According to Tremonti, "We're all very excited to reconnect with our fans and each other after seven long years." He later added that being in Creed again was "the last thing [he] expected." Phillips also stated: "Our career as Creed came to a very abrupt and unforeseen ending. After reflecting on some of the greatest personal and professional moments of our lives, we've come to realize that we are still very capable of continuing that career and our friendship on a grander scale than ever before." In an interview for People magazine, Stapp elaborated on the reunion, saying, "We never felt like we weren't together. We're not looking at this as a reunion. It's more of a rebirth."
In June 2009, Creed performed with Marshall on bass for the first time in eight years on Sessions@AOL, showing the band playing four of their hits. In addition, the band performed live on Fox & Friends on June 26, 2009. Creed's reunion tour, with touring guitarist Eric Friedman, kicked off on August 6, 2009, and concluded on October 20. Full Circle, Creed's first album in eight years, came out on October 27, 2009. Stapp explained the title as follows: "It really defines and articulates, melody-wise and lyrically, what's happened with us. We've come full circle and it's a great place to be." The first single from Full Circle, "Overcome", was posted on the band's official website on August 18, 2009, the same day the radio premiere started along with its release as a digital download on August 25. The second single, "Rain", was released to radio stations on September 23 and became available on October 6, 2009, as another digital download. The third single, "A Thousand Faces", was released in 2010.
On September 25, 2009, Creed performed a concert in Houston, Texas that was recorded, broadcast via a live internet stream, and subsequently released on December 8, 2010, as a concert film titled Creed Live, the band's first live recording. The performance shattered Justin Timberlake's world record for the most cameras used at a live music event by using an unprecedented total of 239. The performance also featured the first usage of the "big freeze" technology, popularized by the 1999 film The Matrix, in a concert environment. Drummer Scott Phillips also confirmed that Full Circle will not be the band's final album. The same announcement confirmed that Creed was to go on a world tour in support of Full Circle between April and September 2010, starting with an Australia/New Zealand tour, followed by South America, Europe, and North America. The tour was called The 20-10 Tour. Tickets for the tour were ten and twenty dollars to stand up against rising concert ticket prices. The first 2,010 tickets purchased for every concert did not include any service fees. Despite these efforts, not every show sold out, and critical reviews were mostly mixed. Skillet joined the tour as main support.
Creed reconvened in late 2011 and early 2012 to begin work on a potential fifth studio album. A tour was also announced in which the band would perform their first two albums, My Own Prison and Human Clay, from front to back over the course of two nights, with selected tracks from Weathered and Full Circle also featured. This tour kicked off with two shows in April 2012, at the Chicago Theatre in Chicago, Illinois, with the band performing My Own Prison the first night and Human Clay the second. They also toured in South America and Indonesia.
