Holiday Harp Music

The Library will be filled with holiday harp music.

  • Take a break from the holiday busy-ness to enjoy some beautiful harp music, courtesy of Glenda Grimmer, a harpist with the Colorado Celtic Harp Society.
  • A library tradition, this concert is always popular with patrons and sets the tone for a peaceful and warm holiday season.
  • In addition to the harp, Grimmer plays piano and flute. She is currently a flutist with the Longmont Concert Band. Grimmer is a Board Certified Music Practitioner and provides therapeutic harp music for hospitals and assisted living facilities.  She is also on the board of the Colorado Celtic Harp Society.
  • No registration is required.

The Friends of the Longmont Library generously support library programs and services.
