Today’s Medford Farmers Market — the annual Apple Fest edition — will feature live music by Kier Byrnes from 3 to 5 p.m. and Wendy Linkin, Nicole Cuff (the 94s) and Stacy Springs (Combo Combo) from 5 to 7 p.m. Byrnes is an award-winning musician based in Medford. His music is self-described as “Good country gone terribly, terribly bad.” Linkin, Cuff and Springs (of Combo Combo) are singer/songwriters. Each will do a short set of covers and originals followed by a set together focused on vocal harmonies. Visit the Farmers Market website for today’s vendor list and more details, including how to sign up for the Apple Fest bake-off by Wednesday. After today, there are two more weeks of the market, which closes on October 17.
