Denver Jazz Fest
April TBD, 2026
Denver enjoys a wealth of local jazz talent, and its unique urban setting is well situated geographically to host celebrated touring artists at various times of the year. These musicians appear in concert venues, local clubs and jazz education programs, as well as gaining indispensable exposure through KUVO — a formidable FM radio station broadcasting jazz in a nonprofit public radio format.
Denver-based jazz industry professionals David Froman and Don Lucoff have collectively spent over 70 years producing and marketing jazz, both locally and internationally. Through their myriad musical experiences, they have come to believe that Denver should be recognized for its time-honored jazz legacy. So, they have conceived Denver Jazz, a Colorado 501 (c)(3) nonprofit organization, and an annual Denver Jazz Fest.
The inaugural festival will be held in venues throughout the Denver and Boulder metro areas. Emphasis will be on Denver’s downtown and the historic Five Points cultural district. April was chosen to coincide with Jazz Appreciation Month (JAM), which celebrates America’s only indigenous art form — recognized by joint houses of Congress as a National Historic Treasure. Also occurring each April is International Jazz Day, which highlights the role of jazz in uniting people worldwide.
