MarchFourth Marching Band

American musical and performance group based in Portland, Oregon. They perform mostly instrumental music, combined with a visual performance by stiltwalkers, acrobatics and hooping. They have toured Germany, The Netherlands, France, British Columbia, China and the United States. MarchFourth performs mostly original works and occasional cover songs. The name derives from the date of the band's creation, March 4, 2003, Fat Tuesday. Within two months of their first show, the local press had already coined a new nickname for the act: M4.
