Think of the pre-2000 music history of Colorado and, depending on your age, you might immediately think of John Denver and Judy Collins. Or maybe your thoughts turn to The Astronauts, Big Head Todd & the Monsters, Firefall, or the String Cheese Incident. While the state is known for many successful recording artists, it is also home to many unacknowledged singers and bands, who released small label shellac and vinyl recordings, and then became lost in the music history of Colorado. Elk Bugles recognizes almost 3,000 lesser-known bands, singers and recordings from the Rocky Mountain State, in a detailed collector’s guidebook of more than 6,000 records listed, complete with photos.
