With Teeth (also known as Halo 19, also printe as [WITH_TEETH]) is the fifth studio album from American industrial rock act Nine Inch Nails. The album was produced by Nine Inch Nails frontman Trent Reznor and long-time collaborator Alan Moulder. Reznor ultimately described the album as “13 songs that are friends with each other.” More specifically, he has indicated that the album is highly influenced by his battle with, and recovery from, alcoholism and substance abuse. This album marked a relative return to the more synthpop sound of the band's 1989 debut Pretty Hate Machine, and is also known for spawning three of Nine Inch Nails's best-known singles: "The Hand That Feeds", "Every Day is Exactly the Same", and "Only". "The Hand That Feeds" is also featured in the popular video game Rock Band. With Teeth is the first Nine Inch Nails album to not feature an instrumental track since Pretty Hate Machine.
