"High of 75" is a song by the Christian rock band Relient K, and it appeared as the third track on their fourth full-length album, Mmhmm. It is also the first and only Christian radio single from the album, although "I So Hate Consequences" and "Life After Death and Taxes (Failure II)" have appeared on ChristianRock.Net. Two more singles were released in the mainstream as well, along with a music video for both. The single was released after "The Truth", which was a Christianradio single off the band's fifth EP, the Apathetic EP, and was followed by two singles from the band's fifth album, Five Score and Seven Years Ago. The song is currently Relient K's twenty-eighth most popular song on iTunes. Thiessen has stated this song was written influenced by the Northern-Ohio's undependable weather.
