Today, the Rock & Roll Hall of Fame will once again offer a free admission day in honor of Dr. Martin Luther King, Jr. Throughout the day, there will be live performances, an art demonstration, education programs and family activities that “highlight how people have used music to find their voice and create a sense of community.” Jason Walker will serve as the MC and DJ for the event, and the Rock Hall will also take donations of hats, scarves, gloves and other cold weather clothes to benefit Clevelanders in need. Check the Rock Hall site for hours. (Niesel)
