Driving in this morning & I'm trying to work out what's playing on the radio ... some kind of ECM Scandi-jazz piano post-Bill Evans with Ravelesque inflections?

No. In fact it was Frank Bridge - one of his 'poems' for piano (Sunset). Gosh.

I knew the name, knew also that he'd been Britten's teacher. But this piece has really piqued my curiosity ...
