The song really portrays the heartbreak of the character, and the murky, unforgiving sea which he has committed to. You can almost see and hear the ocean, and feel the main character as he reflects upon what he's become and what he's lost. The instrumentation is spot on. Like any good post-metal group, every instrument has its say, and everything's beautifully balanced.

There's movement in the song where the main character and his former lover exchange words, presumably over a distance, where the torment and pain of the situation is palpable. The song, and the album's concept in general, really hits my soft spot for stories of pain and failure, and the proverbial fall from grace. It also invokes great imagery.

The 9:52 long track immediately blasts you off your feet with a ethereally heavy series of riffs and Aaron Turner's rough vocals. Keeping it interesting, the structure continues to evolve, and drifts downward into a more dreamy movement which stays dense and builds the tension for the following verses. About halfway in, the song reaches the first climax that (I think) embodies the "Threshold" in the song title. After which, it moves into a more contemplative section, smoothing out the turmoil and tension brought on by the first half, while building its own. Beautifully, it succeeds in building yet another crescendo, only to end in free fall, with guitar and bass fantastically accenting the mood. The bass in this song is truly something to behold, wavering and powerful in its tone.

What I like about this song reflects on why I like Isis' music in general: it's complex, atmospheric, emotional, intricate, and smart. It truly is "thinking man's metal." Isis is all about themes and atmospheres, emotions and vibes, rather than clear ideas and lyrics. It's visceral, raw, and transcendent. And in some ways, I think this song embodies everything that makes them great.

Despite the vocal style of James (not appreciated by myself) this track is a true masterpiece - listful, solemn and mysterious. Numerous good covers inc. Kelly Joe Phelps, & Chris Thomas King (O Brother Where art thou). The original's guitarwork is superior to other versions - sparse and perfectly timed. However Phelps has, in my oppinion, a more appripraite voice for the track.

Acoustic/Punk Rock, I absolutely love this song because of the way it is starts so smooth and slow and then gradually erupts into an amazing finish. It also has great lyrics and a story to it.
