The problem with Hovhaness is that, being loved only on the fringes, performances are often not very good. There is one truly outstanding recording, though: an album titled Celestial Gate, Rudolf Werthen conducting I Fiamminghi (on Telarc). Just gorgeous.

For other music that hits me in similar places, I'd point forward to Górecki and Arvo Pärt*, and backwards to Bruckner.

*late 1970s-80s work in both cases; both had to work their way into their mature styles from rather alarming beginnings
