I know this is kind of late but I didn't find out about this until today.
WELSH composer Karl Jenkins will be honouring Martin Luther King, Jr during a major concert at New York’s Carnegie Hall tonight. The event will open with the world premiere of Jenkins’s Hymn – In Memoriam: Martin Luther King, Jr. Conductor Jonathan Griffith will lead cellist Lori Singer and the Distinguished Concerts Orchestra International in this work.
