Before religion hate took place?

It has the chants in all their 22kHz glory :B

EDIT: seems this Youtube vid has the original as well

Fire, also, is my favorite boss.

I see I forgot the obligatory youtube link to the music.

It's four minutes long, but a good listen for anyone who likes Zelda music.  For those who don't have the time, it goes like this: The first cycle plays when Link has just entered the abandoned castle foyer, and is a quiet, haunting version of the castle theme, with the ending notes of Ganondorf's theme thrown in at the end.  The second cycle now has some ominous bass pervading the theme.  The third cycle adds Ganondorf's music into the harmony, which begins to drown out the quiet castle theme.  By the fourth cycle, when the player is close to Ganondorf, the castle theme has disappeared entirely, replaced by Ganondorf's theme.  The thing that makes this piece work is how the corruption of the theme moves seamlessly with the player's progress, without having to start the piece again from the beginning or having to wait for the right point in the music to change - this is something that can only be done by MIDI music (EDIT: point stricken due to new information in subsequent posts).

So it's a bit like how the music gets more intense in Burnout 2 when you boost, but using some proprietary format where two seperate audio streams are absolutely synched.

It can't only be done in MIDI. Super Mario Galaxy had an orchestrated piece where it changed on the dot whenever you wanted it too, in case you didn't know it's the Bowser fight music. During normal battle it plays the normal song, but the minute you hit him on his back and he starts rolling around, the music changes instantly to a more robust version with vocals.

EDIT: here's a video of it in action (fast forward to the end)

Ah, so it has been done with pre-recorded music streams. Point withdrawn.

Inside the Deku Tree. No doubt.

I like the Fire Temple Music, but also like the Boss Battle Music and Ganondorf's Theme.
