The Brooklyn-based orchestral collective known as The Knights began as an informal gathering of friends to play late night chamber music. Founded by brothers Colin and Eric Jacobsen, the Knights have grown into a variable ensemble that brings the element of surprise back into orchestral concerts. Sometimes that’s in the way they present the music, and sometimes it’s in the music itself, like their collaboration with composer Andy Akiho. Andy’s main instrument in the steel pan, something usually associated with calypso music and almost nothing else. Members of the Knights present a new recording of an Akiho septet, and they’ll also play live in-studio. (From the Archives, 2017.)
