I wasn't familiar with Caul music beforehand, and info is rather hard (for me, at least) to dig out of the web. I've no idea which of the tracks on that page are the most recent five but, in general, I like 'em all.
My favorites are Mirare (love the unleashed awe(?) angst(?) that comes in near 1:20), Aglaia (the bass line and the drawn out tones are perfect together, and I consider any instrumental to be good if I start improvising a vocal melody the first time I hear it), and Aery (I imagined myself standing on a nighttime hilltop with swirls of benevolent turbulence for company).
I was especially taken with the control and emotion in the long tones throughout. And I liked the "rock" feel some of the tracks have. Nicely done.
Is that an actual acoustic bass in Fulgent?
