Marietta’s Cobb Wind Symphony will be headed to the Windy City later this week for an encore performance at a prestigious international music educator’s conference.

The group’s Thursday night concert at Chicago’s McCormick Place convention hall will be the second time the adult community band has performed at the Midwest Clinic International Band and Orchestra Conference, which annually draws about 15,000 high school and college band and orchestra directors from across the U.S. and about 30 other countries.

Each year, the clinic invites about 30 ensembles to come to Chicago and perform. The CWS, which was founded in 1999 and draws musicians from around metro Atlanta and the surrounding area, also played at the conference in 2003.

The 100-plus members of the CWS are led by conductor Alfred Watkins, who has been band director at east Cobb’s Lassiter High School since 1982 and assistant conductor Bob Cowles, retired director of bands at neighboring Walton High.

Also performing at this year’s Midwest Clinic is the Lassiter High School Percussion Ensemble.

Band directors earn continuing education credits for attending clinic seminars, which have been held each December in Chicago since 1946.
