'''To Kill a Demon''' is the eighth track (Disc 1 Track 8) included in ''[[Halo 3: Original Soundtrack]]'', and plays during the ''[[Halo 3]]'' [[campaign]] level ''[[Tsavo Highway]]''. It is composed of ''To Kill a Demon'' (0:00-1:05), ''Ancient Dust'' (1:05-2:07), ''Punch Through'' (2:07-2:58), and ''Underestimated'' (2:58-3:42).

==Overview==
===To Kill a Demon===
''To Kill a Demon'' (1:05) begins with ambiance invoking the atmosphere of a dry desert. Low strings enter, playing a heavy melody as a low-strings-only version of ''To Turn a Tide'' (from the later track ''[[This is Our Land]]''), but soon fade out as the ambiance take over completely. This piece plays when [[John-117]] and his [[UNSC Marine Corps|Marine forces]] defend their position against [[Type-52 Phantom]]s after crossing the broken bridge.

===Ancient Dust===
''Ancient Dust'' (1:02) fades in with heavy percussion and low strings playing the triplet rhythm from the ''[[Halo Theme]]'' in repeat. The percussive beats and low strings crescendos into a series of cymbal clashes to end the piece. The piece plays during the encounter with [[Type-26 Wraith]]s at the cliffside overlooking the [[Portal at Voi]], and in the level ''[[Halo (Halo 3 level)|Halo]]'' at the start of the Warthog run.

===Push Through===
''Push Through'' (0:51) begins with digital notes and sound effects playing in soft ambiance. The short piece ends as vocals and strings take over the digital sounds effects to transition into the next section. The piece plays during the final encounter of the level, where John-117 defeats a [[Jiralhanae]] pack led by a [[Jiralhanae War Chieftain]] at the tunnel entrance leading into [[Voi]].

===Underestimated===
''Underestimated'' (0:44) features the percussion from the later track ''[[Farthest Outpost]]'', opening with muted drums, then leading into percussive beats played using snare drums and hi-hat. High strings enter with the melody of ''[[Under Cover of Night]]'' (from ''[[Halo: Original Soundtrack]]'', though the piece ends after one phrase of the melody. The piece plays during the ending cinematic of the level, in which [[Miranda Keyes]] reports to [[Terrence Hood|Lord Hood]].

==Production notes==
The name of the soundtrack alludes to "[[Covenant religion#Demons|Demon]]", the title the Covenant has given to Spartans, and may be a reference to the book ''[[Wikipedia:To Kill a Mockingbird|To Kill a Mockingbird]]'' by Harper Lee.
