Matt Mulqueen was born and raised in Baltimore, Maryland, in a musical family. His siblings danced and played the button accordion and fiddle, and Matt grew up singing in the choir and playing piano.  As a young man, he began taking lessons with pianist Donna Long, who taught him how to play and accompany Irish traditional music. Matt became a part of the fabric of Baltimore’s Irish music community, and was a regular at the long-running session at J Patrick’s before later becoming a fixture in the Baltimore session scene, hosting the sessions at Cafe Hon, Zissimo’s, Mick O’Shea’s, Racer’s, and the Green Room.

Matt is a sought after accompanist, and can be heard accompanying fiddler Rosie Shipley on At home (2002), Dylan Foley and Josh Dukes on The New York Connection (2016), Kieran Jordan, Sean McComiskey, and Seán Clohessy on Cover the Buckle (2016), Dylan Foley on Deliriously Happy (2017), and Joanna Clare on To Keep the Candle Burning (2022).  He was also a founfinf member of the Old Bay Ceili Band, competing with them twice in Ireland, and recording Crabs in the Skillet (2011).  He regularly tours and performs with some of the most decorated musicians playing today, including Frankie Gavin, John Whelan, Diarmuid Ó Meachair, Nathan Gourley, Laura Feddersen, Andrew Caden, and more.

In addition to teaching students privately and for the Baltimore Irish Music School, Matt has been on instructional staff at the Baltimore Irish Trad Fest, Augusta, and DC MAD Week.
Listening to the host of traditional musicians who haunt Irish pubs and to innumerable recordings allowed Matt to forge his own compelling style of accompanying Irish music.
