Jam Sessions


The Boulder Friends of Jazz hires a rhythm section, or “back line” of three musicians to ensure that there will be good quality accompaniment for any musician who happens to drop in. A Jam Leader is hired on a rotating basis to lead off the jam and to ensure that any musician in attendance gets adequate time to play in the jam. Prior to the jam, the Guest Director engages two additional musicians to round out the front line. All three members of the front line as well as the three musicians in the rhythm section are paid for their performances at the jam. Door prizes are awarded to those in attendance based upon ticket drawings. Members and guests are eligible for such prizes as have been donated by local merchants and musicians. Examples are dinners in local restaurants and CDs of the musicians in attendance. The Denver Jazz Club often provides free admission to its concerts as door prizes. 


Jam Sessions are held the first Sunday of the month from 1-4pm.


The monthly jams are held at the Avalon Ballroom,  6185 Arapahoe Rd, Boulder, CO. It is located slightly west of 63rd Street on the north side of Arapahoe.

Parking & Refreshments

The Ballroom has ample parking, but no bar or kitchen facilities.  So BYOB, snacks, etc. and come out and enjoy the jam.
