"Wolf" is a song by the American heavy metal band Iced Earth off their 2001 album Horror Show. The song may be the heaviest song of the album, and also one of the most technical. It starts out in what can be described as almost like a jam session, with the minor key guitars setting the tone for virtually the rest of the album. At 00:45 the song changes direction, kicked off by a powerful F#5 delivered by vocalist Matt Barlow, which he harmonizes with a Bb5, his highest note ever recorded, then morphs the notes into wolfen howls and holds out until 1:00, when the first verse begins. At which time, the band comes together to create a gallop, backing the theatrical, now tenor stylings of Barlow.
