Bassist Mike McGuirk grew up in Portland, Oregon. At age eleven he began playing the electric bass and, while in high school, devoted his attention to the acoustic bass. He went on to study at the University of North Texas with Jeff Bradetich, where he received a bachelor's degree in Jazz Studies.
In 1997, he won the International Society of Bassists jazz bass competition. Since arriving in New York he has played and/or recorded with John Abercrombie, Marc Copland, David Liebman, Tim Hagans, Don Friedman, Joey Baron, Andy Laverne, Eliot Zigmund, Adam Nussbaum, Bennie Wallace, Mulgrew Miller, Billy Drummond, Renee Rosnes, Walt Weiskopf and Eddie Henderson among others.
Recently, he can be heard on Marc Copland's Lunar featuring David Liebman, and Jed Levy's Round and Round on Steeplechase records.
