Hot Streets is the tenth studio album (twelfth overall) by the American band Chicago, released in 1978. In many ways, Hot Streets marked the beginning of a new era for the band, turning to disco music, a move which would be derided in retrospect. It was also the band's first album with all-new material released since their second that didn't have a numbered title. It was also the first album not to feature original guitarist/vocalist Terry Kath, who died from an accidental self-inflicted gunshot wound in January 1978. He was replaced by Donnie Dacus on this album.
