is right: it does
sound a lot like David Arkenstone... ...I'm having to work from memory here, because I haven't listened to my Arkenstone CDs in 10-15 years, and they're all inaccessible in a distant storage unit right now. But this particular song seems familiar (...it's a little hard to tell because they're all similar sounding "meandering" instrumental music without strong melody lines, and tend to blur together, at least for me
If it is Arkenstone, I think it's from one of his Narada or Windham Hill releases in the early to mid-1990s, and I'm guessing maybe it's on his Chronicles compilation, or possibly his Convergence compilation with David Lanz. (But it also might be familiar to me because (per Wikipedia
) he's composed several film and video-game scores.) If it's not him, I still think it might be a Narada or Windham Hill release from the early to mid-90s, but I can't think who the artist would be right now.
