Rhythm on the River Festival Guide


History of Rhythm on the River

Rhythm on the River began in 1995 as a small celebration for the opening of Roger’s Grove along the St. Vrain Greenway. Roger Jones was an avid outdoors person whose dream was to give the community a park / arboretum to visit in the middle of the city. In 1995, the family donated funds to the city for the purchase of the property adjacent to the Boulder County Fairgrounds. He and his wife also had a passion for music and art, hence the name Rhythm on the River. The event theme was created around the environment and the Jones's passions for the arts. In the beginning, a few vendors and two bands entertained visitors. Since that first year, the event has kept with the theme of educating the visitors through music, art and interactive components.
