Lundell made his debut in 1975 with the LP "Vargmåne" and was immediately hailed as "Sweden's Bob Dylan". In 1976 his first novel, the partly autobiographical Jack was published by Wahlström & Widstrand. Lundell was influenced by musicians such as Bruce Springsteen, Bob Dylan, Neil Young and writers such as Jack Kerouac, Allen Ginsberg and other beats.
Lundell is one of the central figures in Swedish rock music and he is one of the most important influences on Swedish musicians writing and singing in Swedish. Lundell is also somewhat controversial and has argued with everyone from neo-nazis, feminists and communists to colleagues.
Lundell was known as a heavy drinker and alcoholic in the 80's. He once said that "a cancelled gig is also a gig" after he had cancelled a concert in Hultsfred because he was drunk. In the late eighties he submitted himself to a clinic and he has been clean since 1993.
His biggest hit was "Öppna landskap" from 1982, a song once proposed to be Sweden's new national anthem.
