Matthew Arnold Thiessen (born August 12, 1980) is a Canadian-born American musician known for being co-founder, lead singer, guitarist, pianist, and primary songwriter for the rock band Relient K. With Relient K, he has released eight full-length albums, including three that were certified Gold, and three that peaked in the top twenty on the Billboard 200. Outside of his work with Relient K, Thiessen leads a side project called Matthew Thiessen and the Earthquakes, which released its debut album Wind Up Bird in 2018. In 2009, he co-produced and collaborated on Owl City's album Ocean Eyes.

Thiessen founded Relient K in 1998, with guitarist Matt Hoopes, and bassist Brian Pittman,^[1] and recorded the demo All Work & No Play the same year. The recording attracted the interest of Toby McKeehan who signed the band to his label Gotee Records. Between the years 2000 and 2003, Gotee released three full-length albums, one Christmas album, and four EPs with Relient K. In 2004, their fourth album Mmhmm was released on both Capitol Records and Gotee, and peaked at number fifteen on the Billboard 200.^[2] After recording another EP in 2005, Mmhmm and Two Lefts Don't Make a Right...but Three Do, their 2003 album, were certified gold, followed by their 2001 album The Anatomy of the Tongue in Cheek in 2006.^[3] In 2007, Gotee, Capitol, and EMI released Relient K's fifth studio album, Five Score and Seven Years Ago, which peaked at number six on the Billboard 200.^[2] After the release of the double EP The Bird and the Bee Sides in 2008, the band signed with Gotee's Mono Vs. Stereo imprint, on which they released their sixth studio album, Forget and Not Slow Down, again reaching the top twenty of the Billboard 200.^[2] Thiessen and the other members of Relient K have taken up A&R positions for the label as part of the record deal.^[4]

Thiessen has been the lead vocalist, frontman, guitarist, primary songwriter, and, along with guitarist/backing vocalist Matt Hoopes, the only member who has been in the band for its entire history. Because of this position of musical leader, he maintains the most creative and artistic control of the band members.^[5] He has also served as co-producer on several occasions as well. As the band matured musically, Thiessen started being credited with piano in most releases, beginning with The Anatomy of the Tongue in Cheek in 2001. Since the release of Mmhmm in 2004, his piano playing started becoming more prominent, and he began including a piano onstage as well.^[6]

In addition to being in Relient K, Thiessen plays in his own solo piano project called Matthew Thiessen and the Earthquakes. Prior to 2018, the project had released a total of five songs on various samplers and compilation albums from Gotee and Mono Vs. Stereo, and several songs written for the project have been re-recorded on Relient K releases. In 2010, after the release and supporting tour of Forget and Not Slow Down, Thiessen announced that he would begin work on a full-length solo album.^[7] Although he had previously expressed interest in recording a studio release, he had placed his priority on Relient K, and relegated his solo work to his free time.^[5]

In April 2018, Adam Young of Owl City announced that Matthew Thiessen and the Earthquakes would be joining them on tour later in the year.^[8] In June 2018, Thiessen announced that his debut album under Matthew Thiessen and the Earthquakes, Wind Up Bird, would release later that summer.^[9]

Thiessen has occasionally collaborated with Jon Foreman of Switchfoot. After initial interest in recording vocals for a Switchfoot song, it instead worked out for Foreman to contribute vocals for the Relient K song "Deathbed" from Five Score and Seven Years Ago.^[10] He later contributed songwriting and vocals to the Switchfoot release "Rebuild" in 2007, in conjunction for the Appetite for Construction Tour.

In 2009, he contributed vocals, songwriting, and production to Owl City's major-label debut Ocean Eyes, which has sold over 1,500,000 copies worldwide and reached the top ten on the Billboard 200.^[11] Lead single "Fireflies" reached number one on the Billboard Hot 100 in late October, and was a global success, topping the charts in many countries including Australia, Denmark, the Netherlands, and the United Kingdom.^[12] Thiessen continues to work with Owl City's Adam Young and contributes vocals to "Plant Life", a song on the album, "All Things Bright and Beautiful". He also co-wrote "Good Time" with Owl City and Brian Lee.^{[citation needed]} Thiessen has also made guest contributions on a number of releases with other artists, including Blackbear, John Reuben, tobyMac and The Fold.^{[citation needed]}

Thiessen has received piano lessons since he was seven years old, with early interests in ragtime and Scott Joplin, specifically the soundtrack from The Sting. He taught himself guitar at the age of 14 by learning to play songs by grunge bands like Silverchair and Nirvana. Thiessen does not use guitar picks while playing; he instead uses his thumb. According to Matt Hoopes, this is because he can't.^[13] Since Relient K's early days, Thiessen's main influences have been in the pop punk genre,^[6] specifically NOFX, Less Than Jake, Ghoti Hook, MxPx,^[5] and Goldfinger.^[14] He later introduced influences from Simon & Garfunkel, Ben Folds, and The Beach Boys,^[6] whom he has named as his favorite band.^[5] Thiessen has claimed that after years of writing and performing pop-punk songs, he now finds writing slower music more enjoyable.^[14] He has described his Matt Thiessen and the Earthquakes side project as being influenced by Rufus Wainwright and Ben Folds.^[6]

Though he has played several guitars throughout his career, Thiessen is best known for playing Gibson ES-335s and has also been seen playing a Gibson Tom DeLonge Signature ES-333 occasionally.^[15]

Thiessen was born in St. Catharines, Ontario. His parents divorced when he was six years old and living in Stevensville, Ontario. Later, his mother remarried and the family moved to Bolivar, Ohio, where he met and befriended future bandmates Matt Hoopes and Brian Pittman. The three have said that they have known each other since first or second grade.^[16]

Thiessen dated future pop star Katy Perry for a time from 2003 until 2005, and wrote several songs with her and Glen Ballard during her early recording sessions. One of the songs the three wrote, "Long Shot", would go on to be recorded by Kelly Clarkson on her 2009 album All I Ever Wanted.^[17] Remaining on good terms with Perry, he also co-wrote "Dressin' Up from Teenage Dream: The Complete Confection.

In 2008, it was announced that Thiessen proposed to Shannon Murphy, a morning radio co-host of the "Mojo in the Morning" show based in Detroit. The couple planned for an August 22, 2009 wedding.^[18] However, the engagement was terminated in December of that year. Murphy later reported that, though they were no longer together, they were on good terms.^[19]

Thiessen married Emily Wright on August 23, 2015, in New York City, with Matt Hoopes as his best man. They kept the engagement and marriage a secret from the public.^[20] The couple divorced in February 2018.^[21]
