The recording attracted the interest of [[TobyMac|Toby McKeehan]] who signed the band to his label [[Gotee Records]]. Between the years 2000 and 2003, Gotee released three full-length [[album]]s, one Christmas album, and four [[extended play|EP]]s with Relient K.

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.<ref name="Christian Music Today" /> 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.<ref name="liveDaily">{{Cite web |last=Zulaica |first=Don |date=January 27, 2005 |title=liveDaily Interview: Matt Thiessen of Relient K |url=http://www.livedaily.com/news/7609.html |url-status=dead |archive-url=https://web.archive.org/web/20091123111026/http://www.livedaily.com/news/7609.html |archive-date=November 23, 2009 |access-date=October 24, 2009 |publisher=[[liveDaily]] }}</ref>
