Kara-Lis Coverdale presents a program of solo piano works, A Series of Actions in a Sphere of Forever, in PS21’s Black Box Theater. Taken from her recent album of the same name, the works are in a way classic nocturnes (i.e. inspired by night), but also evoke tangential, abstract associations: an animation of melodic webs; moving through a thick substance; sound objects in space. Written and recorded during winter in a small rural studio in Ontario, they also reflect Coverdale’s retreat from maximal sound and a return to acoustic fundamentals.
