A couple planks of wood might not sound like the most riveting orchestration—but it turns out the musical possibilities are endless!

This Saturday on Second Inversion: Knock on Wood! We’ll hear from composers who have built entirely new sound worlds from some very humble lumber. From the warm wooden tones of the marimba to literal two-by-four planks of wood, we’ll hear from artists who have logged some serious hours exploring the timbre of—well, timber.

To listen, tune in to KING FM on Saturday, July 31 at 9pm PT.
