The Rocky Mountain Music Association was once the primary advocate for local musicians in these parts, but over time the group grew less and less effective, causing one wag to joke that anything sponsored by the RMMA "couldn't draw flies." Now the Colorado Music Association, or COMA, has undertaken the same mission with an energy and drive that can't be denied; in its first year of existence, membership has grown from the tens to the hundreds. In addition, the group has a first-rate Web site (www.coloradomusic.org) and sponsors concerts, discussions and workshops that people actually attend. Imagine that.
