There may be something called "confirmation bias" occurring here but tonight, counterstream radio is streaming Ingram Marshall's Authentic Presence, as played by Sarah Cahill. Just last weekend, I was thinking this is one of the composer's "a" works.
From an Amazon review:
Also included on this CD is the more recent solo piano work, Authentic Presence, performed by New Music pianist extraordinaire Sarah Cahill -- without any electronic bells and whistles. It's nice to hear Marshall's music in a more intimate, acoustic setting like this, and while this piece sounds a lot like Phrygian Gates by John Adams at times, it packs a bigger dramatic punch and has a lot more emotional contrast (not to mention many fewer notes.)
prior "a" works this week: music in similar motion.
