Jeff Conner, a trumpet player with the Boston Brass, a world-renowned quintet, assisted Chillicothe High School Band Director Sarah Cavanah for the first three days of band camp. Conner, a founding member with the Brass, lives in the Boston area and he and the rest of the ensemble travel the world and strongly believe in music education. The Boston Brass will return to Chillicothe on March 6 for the CHS Celebrity Band Concert. Conner worked with the band and did fundamental music rehearsals Monday through Wednesday of this week. Band camp continues through Friday, from noon to 4 p.m. at CHS.
