On this week’s Modern Notebook with Tyler Kline: Perforation, by Alex Burtzos, is an exploration of grief, presented in a deliberately stripped-down, bare sonic environment. In this solo piano work, the composers leverage pulse, repetition, and silence to respond to the raw and direct emotionality of words by poet Cristin O’Keefe Aptowicz.

Then: There is a Buddhist concept that says, “if we fully accept that nothing lasts, then we may take a step - by letting go - towards finding tranquillity.” Composer Michael Zev Gordon likes this sentiment - but, in contrast, he also acknowledges his connection to things: remembered, passing, desired.
