Treehouse is the upcoming fifth studio album by American rock band I See Stars, set for released on June 17, 2016 through Sumerian. It is the first studio album by the band not to feature vocalist/keyboardist Zach Johnson and guitarist Jimmy Gregerson, whom were both asked to leave the band in 2015. It will also be the band's first album since 2013's New Demons, marking it the longest gap in between album releases. 　　Vocalist Devin Oliver said of it:“This is the most time we’ve had to create an album since ‘3D‘. We actually had time to reflect on our past, but most importantly what we want to become. Beyond the music, it felt like an evolution for us emotionally. We finally feel like the band we were meant to be. If you strip it down, it’s not just drums, guitar, bass, vocals, and minor production. The electronic aspects could be their own songs, and we aim to blend everything as seamlessly as possible.” 　　The band enlisted numerous producers for the album, including David Bendeth (Bring Me The Horizon, Of Mice & Men), Taylor Larson (Periphery, Veil Of Maya), Nick Scott (Asking Alexandria, Chunk! No, Captain Chunk!) and Erik Ron (Panic! At The Disco, Saosin).
