The Redwalls are a two-member rock band from Deerfield, Illinois, in suburban Chicago.

Nearly two years after Universal Blues the band would release their second studio album (first under Capitol Records), titled De Nova, on June 21, 2005. Shortly after, The Redwalls were invited to join Oasis on their Summer 2005 UK tour and were also featured at Lollapalooza in 2005 & 2006. In 2007, The Redwalls finished recording material for their third studio album, however before its release, the band was dropped from Capitol Records. They quickly signed with indie label MAD Dragon Records and their album The Redwalls was later released on October 23, 2007. In addition, their song "Build a Bridge" was featured on an AT&T commercial. By 2008, the band had achieved moderate success and began their highly successful US tour, which culminated with performances on The Late Show with David Letterman and The Tonight Show with Jay Leno on April 10, 2008. In the latter part of 2008, The Redwalls once again began touring in the UK, this time supporting The Zutons. However, lead guitarist Andrew Langer, as well as drummer Rob Jensen, left the group to focus on other musical projects.
