Possibly a reference to The Whole music venue in Coffman Union at the University of Minnesota (http://www.coffman.umn.edu/whole/). According to a post on the Unified Scene, "it used to have lots of all ages shows with some great bands."
From the University of Minnesota web site (previously cited):
"Since it’s inception in the 1960’s, the Whole Music Club has contributed to the cultivation of a huge, and diverse music community in the Twin Cities. What began as a coffeehouse for students to perform and study, quickly evolved into a nationally renowned venue that offers students the opportunity to see local and national music icons for affordable prices in the basement of Coffman Memorial Union on the University of Minnesota East Bank campus.
"The Whole is located in the Basement of Coffman Memorial Union."
