What song is playing during the first encounter with Granzeboma? During Tengen Toppa Gurren Lagann: Lagann-hen (the second movie), the protagonists encounter Granzeboma at about 01:32:30 into the movie, and a battle begins. (A clip of the scene can be found here; the music begins about 10 seconds in.)



I've listened to as many of the songs in the OST as I can find, and none match this noble, battle-laden theme. What music is it that plays during this scene? Is it even available?
It is from the second OST, track 6, titled BafBaf! そんなに燃えるのが…好きかい ("BafBaf! Sonna ni Moeru no ga...Suki Kai?", "BafBaf! Being Fired Up Like This... Don't You Like It?"). 

The scene in the question starts playing from around 02:28 into the track.

The song was also featured in Gurren Lagann Parallel Works music video #2.
