Ryan Daniel Martinie (born August 6, 1975 in Peoria, Illinois) is an American bassist, best known for his work with American heavy metal band Mudvayne.
Ryan’s career started in the 1990’s as the bassist for Broken Altar. After Mudvayne’s initial bassist, Shawn Barclay, left the band in 1997, the band asked Martinie to join the band in 1998. Although initially hesitant, Ryan joined after realizing the band was serious and has recorded 5 albums with the band: L.D. 50 (2000), The End of All Things to Come (2002), Lost and Found (2005), The New Game (2008), and Mudvayne (2009). Ryan would go under the stage name Ryknow until 2003 when the band decided to ditch their alter egos to avoid comparison with Slipknot.
After Mudvayne went on hiatus in the early 2010’s, Ryan joined Kurai, a project with Scott Von Heldt on guitars and vocals and Abel Vallejo, a drum technician for nü metal band Korn, on drums. The band would release an EP, Breaking the Broken, on December 17th, 2013.
Afterwards, Ryan joined jazz fusion band Soften the Glare in 2015 before Mudvayne announced their reunion on April 19th, 2021.
He is well known for his complex basslines and unique playing style, taking influence from Jimi Hendrix, The Beatles, and Beastie Boys.
