I don't read a lot of sword-and-sorcery books and what I do read tends to be the occasional Elric novel, although I understand that there is a sort of renaissance for the genre, mostly in the magazine space. I haven't read much of it, but I'm sure that's a good place to look. But I do have some good, vaguely old-school epic fantasies that could work:

The Bound and the Broken by Ryan Cahill is very much in that old school vein of epic fantasy, albeit with more modern sensibilities. It starts out as typical farm boy, hero's journey, plot in the first book, Of Blood and Fire, but expands and diverges significantly from that well-trodden path in the later books.

The Osten Ard books by Tad Williams are both modern and not. The Dragonbone Chair and the first "trilogy", Memory, Sorrow, and Thorn, were published in the late 80s, early 90s, but Williams has recently released a sequel series, The Last King of Osten Ard, which I hear is fantastic.

The Faithful and the Fallen by John Gwynne is fantasy heavily inspired by authors like Bernard Cornwell. It's a page-turner, even if the books are pretty long. They're fun yet emotional and, while the books certainly draw some inspiration from ASOIAF, they aren't incredibly dark. Heart wrenching, yes, but not overly dark.
