The band has received local recognition,[4][6] winning multiple Central Pennsylvania Music Awards,[7][8] and maintains a presence across the Mid-Atlantic region.

[4][7][9] The Unforgettable Big Band was founded in the summer of 2000 by saxophonist Steve Spangler in Lake Meade, near East Berlin, Pennsylvania.

Initially, a small group of local musicians gathered biweekly in Spangler’s garage to play big band music.

As its reputation grew, the band acquired a sound system and stage lighting, and rehearsals were moved to First Presbyterian Church in York.
