The Beta Nu Chapter of Phi Mu Alpha Sinfonia, a national music fraternity, began sponsoring an annual jazz concert at UNI in February 1951. The first show consisted of several musicians gathered in the student union, called the Commons, and jamming. By 1953, the show, called "Dimensions in Jazz", had gained such popularity that two shows were scheduled. Performing at the concerts were jazz band ensembles and choruses. The clips of music in this collection are from recordings made of number of those lively concerts.
