Wow, I've known of some orchestrated Zelda music, but this Zelda Reorchestrated project totally flew under my radar. Spent a good few hours listening to music from the site last night, and I can only conclude that it's fantastic stuff.
OCReMix is indeed a great spot for some of the best fan arrangements of popular Zelda tuneage. Keeping in theme with the thread's focus on orchestrated goodness, I'd recommend Tyler Heath's
A Storm in the Desert, a great remix that's dripping with high production values. He also did an awesome take on the Shadow Temple and Temple of Time themes from OoT in a mix titled Shadows Left by Time, but I can't find a mirror for that piece anymore.
