Grammatrain is a grunge rock band from Seattle, Washington from the mid 1990s. Their sound was heavily influenced by bands such as Soundgarden, Nirvana, Metallica, Pearl Jam, and Led Zeppelin, yet it was still distinctive in its own right, and certainly unique among bands marketed to Christians. The band recorded a self-titled demo containing mostly live acoustic numbers in 1994. After signing with Christian label Forefront Records, they quickly followed with their first studio album, Lonely House.
