Persons attending the Sept. 15 Ada Harvest and Herb Festival are in for an entertaining musical treat. Lori Fithian brings Drummunity to the fest' with a 1 p.m. performance in the depot park.  Drummunity is an interactive program for all kinds of groups. It’s not a “show” to sit back and watch. Everyone participates - from 10 to 400 or more people - all playing together. Using hand drums, percussion, and simple drum circle games, Fithian creates a positive, non-competitive experience for people of all ages and abilities to share. Ada Public Library sponsors Drummunity.
