Ridgefield\u2019s celebration of Martin Luther King Jr. Day will be highlighted by music \u2014 from Broadway performers Daniel C. Levine, Katie Diamond and Bryan Perri to rock-jazz fusion band Project Grand Slam to the Ridgefield Chorale \u2014 as well as readings and thoughts on the legacy of the slain civil rights leader. The event is Monday, Jan. 15, from 3 to 4:30 at the Ridgefield Playhouse. It\u2019s free to all. \u201cThe King holiday serves as a focal point for establishing and maintaining community service involving millions of Americans throughout the year to address critical social problems of this nation and to help improve the quality of life for humankind,\u201d said Mark Robinson, who has been organizing the town\u2019s ceremony for 20 years and is a former member of the state\u2019s Martin\u00a0Luther King Jr. Holiday Commission. At this year\u2019s ceremonies, the town\u2019s Spirit of Dr. King Community Service Award will be given to Lori Berisford, SPHERE\u2019s president and board chairwoman and a volunteer at numerous other charitable organizations.\u00a0 Begun in 1997 by Robinson \u2014 and with the support and participation of First Selectman Rudy Marconi since he took office in 1999, the King Day observances have become a community tradition, drawing audiences as large as 200 since being relocated to the Ridgefield Playhouse four years ago.
