The concert will take place at Martin Luther King Jr. High School at 7:30 p.m. Free tickets can be reserved starting January 3 by calling 215-893-1999 or visiting wwww.philorch/mlk.

The Philadelphia Orchestra has performed a concert in tribute to King every year since 1991, but it has never before presented the concert outside of the Kimmel Center or its former home, the Academy of Music.

"I am very proud to be able to announce that the Philadelphia Orchestra is taking our Martin Luther King Jr. tribute concert into the community, and presenting it free to the public for the first time," said Harold A. Sorgenti, the orchestra's incoming chair. "This continues the Orchestra's commitment to celebrating the legacy of Martin Luther King Jr. and [to] taking our music out of the concert hall and into the community."
