Today’s Medford Farmers Market will feature live music by Scratch from 5 to 7 p.m. Scratch is your classic above the garage rock band of romantics and poets. Featuring current and former academics from Tufts University and nearby schools, they play a mélange of rock covers from across the decades. Among today’s 24 vendors will be Justin’s Woodshop. Visit the Farmers Market website for today’s full vendor list and more details. After today, there are four weeks left of the market, which closes on October 17.
