The Mission Mountain Wood Band, abbreviated M2WB, is an American bluegrass and country rock band formed in Missoula, Montana, US in 1971. They were noted for their vocal harmonies, multi-instrumental talent, and charismatic stage presence, particularly at Woodstock style regional concerts of the era such as the University of Montana's Aber Day Kegger. They spent time in New York City to further build their career, appeared on national television and toured 47 of the lower 48 states in a unique 1955 Greyhound Scenicruiser, performing up to 320 times a year both solo and as an opening act for other bands. The original five members were Rob Quist, Steve Riddle, Christian Johnson, Greg Reichenberg, and the late Terry Robinson, all of whom were UM students and born in Montana. Johnson was replaced with Kurt Bergeron after the band released their first album, In Without Knocking, in 1977. The band recorded two studio albums in their heyday, a third album after the band revamped as ‘’Montana’’, released a compilation of their older work in 2005, and put out two albums with new content in 2011 and 2014.

The GMC PD-4501 Scenicruiser, manufactured by General Motors (GM) for Greyhound Lines, Inc., was a three-axle monocoque two-level coach that Greyhound used from July 1954 into the mid-1970s. 1001 were made between 1954 and 1956.
