Krieger wrote or co-wrote many of the Doors' songs, including the hits "Light My Fire", "Love Me Two Times", "Touch Me", and "Love Her Madly". When the Doors disbanded shortly after the death of lead singer Jim Morrison, Krieger continued to perform and record with other musicians including former Doors bandmates John Densmore and Ray Manzarek. In the 2023 edition of Rolling Stones's 250 Greatest guitarists of all time, he was repositioned at number 248.

The Doors were an American rock band formed in Los Angeles in 1965, with vocalist Jim Morrison, keyboardist Ray Manzarek, guitarist Robby Krieger and drummer John Densmore. They were among the most influential and controversial rock acts of the 1960s, primarily due to Morrison's lyrics and voice, along with his erratic stage persona and legal issues. The group is widely regarded as an important figure of the era's counterculture.
