The City of Medford concludes its free Condon Shell Summer Concert series with a performance by the vintage rock band Say Darling (postponed from its original date of June 20 due to weather). Founded by old friends Celia Woodsmith and Chris Hersch, Say Darling evokes the funky drive of Little Feat, the moving vocals of Bonnie Raitt, and the instrumental prowess of the Tedeschi-Trucks Band. Bring a chair or blanket and a picnic, or stop by the Medford Farmers Market to grab some food. Medford Brewing Company will be providing a neighboring beer garden.
