Keller Hall, with its magnificent Holtkamp organ and its marvelous recording capability, is the main performance site of the Department of Music. With a seating capacity of 330, Keller Hall houses over 150 concerts per year, including student soloists and ensembles, chamber groups, and guest artists. Two annual music events mark the calendar: The Keller Hall Series, a distinguished series of chamber music and solo performances by UNM faculty artists, and the Composers' Symposium, a week of concerts and lectures by regional, national and international composers.
