Missio (often stylized MISSIO) is an American pop rock duo formed in 2014 in Austin, Texas. It currently consists of founding member Matthew Brue (vocals, producer), and David Butler (producer, instrumentalist). Missio was formed in 2014 by songwriter/vocalist Matthew Brue. After the completion of his demos, Brue hired friend and local producer/engineer David Butler to collaborate on the self-titled EP, which would later be released in November 2014. After unexpected online success, Brue made his debut appearance under the name MISSIO at the SXSW festival in 2015 with help from friend/producer David Butler. Matthew invited David to officially join in July 2015. During an interview, Brue explained that the name MISSIO comes from the Latin word for "mission." This phrase is significant to him because it is reminiscent of the time period in his life when he was recovering from an addiction, and as a result, had the word tattooed on his arm. In 2017, they signed a record deal with RCA Records and released the single "Middle Fingers", which peaked at No. 9 on the Alternative Songs chart. Missio's debut album, Loner, was released May 19, 2017.
