While he is no longer with us, I suggest David Gemmell. He was one of the world's best in heroic fiction. While his plots were fairly basic, and many of his peers called him "the thirty word author" (he did not use alot of elaborate language) he wrote incredibly intriguing and powerful characters.
He is most famous for his Drenai Series.
(In Chronological order, not publishing order)
Waylander
Waylander 2 (UK title, in America it was called 'In the Realm of the Wolf')
Hero in the Shadows (A Waylander novel, could be considered a trilogy with the previous 2)
Druss the Legend
Legend of the Deathwalker (A Druss the Legend Novel)
White Wolff (A Skilgannon novel, but featuring Druss)
Legend (His first novel, a Druss the Legend Adventure)
King Beyond the Gate (stand-alone)
Quest For Lost Heroes (Stand-alone)
Winter Warriors (Stand-alone, but connected to Hero in the Shadows)
The Swords of Night and Day (A Skilgannon novel)
I might have missed a few.
He also wrote a fantastic four book series called the Rigante Saga.
Sword in the Storm
Midnight Falcon
Ravenheart (this is probably the only book I have ever shed a tear in)
Stormrider.
He has several other standalone and smaller series. Right before his death he wrote a retelling of Troy which encompassed a Trilogy (he actually died halfway through the final one, his wife finished it). Good books, an interesting take on the old Legend.
Lord of the Silver Bow
Shield of Thunder
Fall of Troy
I do agree on the George RR Martin suggestions, and have been meaning to pick up the Black Company series.
As for RA Salvatore's Drizzt series... he has come along way as an author (dude's got some cajones for writing Chewbacca's death) but I strongly dislike the early Dark Elves books... Drizzt was far to much of a Gary Stu. He was not even supposed to be the main character of the series, heck he did not even want to use Drizzt, his original treatment had a character another author wrote and killed.
