The Rose Tree Summer Festival in Rose Tree Park is entering its final week of entertainment for the community. Cimarron 615 offers a distinctive blend of country, rock, and layered vocal harmonies with Bickhardt's American folk and roots music. Come out on Saturday, Aug. 15, for 1970s disco and a Motown revue with the Discoteks. Established in 2014 by Odell Mickens, a former bassist for The Trammps, the eight-piece band offers horns, harmony vocals, and sequined costumes created to get crowds on their feet and dancing. The 11-member horn band features four vocalists complemented by classic soul, Motown, R&B, and disco.
