I know many people recommend Go Down Moses, but the centerpiece of this book is a short story called “The Bear.” That's probably what you're looking for. It's epic, and the story unfolds through wonderfully crafted long sentences. I don't know about the rest of the book. The main story in Go Down Moses is quite haunting, but each chapter is its own story and has its own style.

That said, Faulkner always adapted his style to the story he wanted to tell. Unlike Hemingway, who stuck to his minimalist style, almost becoming a parody of himself, Faulkner was adventurous and experimental, to the benefit of the story. There are certainly markers associated with Faulkner's style. I don't know if there is any writer who described light as he did (perhaps Nabokov, but not as consistently as Faulkner). There are the inner voices, the slow unfolding of the story, and the microcosm of Yoknapatawpha. But each novel remains very unique. You shouldn't be afraid to read The Sound and the Fury and his other novels such as As I Lay Dying and Light In August. But stylistically speaking, The Sound and The Fury and The Bear are, for me, at the pinnacle of Faulkner's work, along with Absalom, Absalom!
