James Douglas "Jim" Morrison was an American singer-songwriter and poet, best remembered as the lead singer of Los Angeles rock band The Doors. From a young age, Morrison developed an alcohol dependency which led to his death at the age of 27 in Paris. He is alleged to have died of a heroin overdose, but as no autopsy was performed, the exact cause of his death is still disputed. Morrison was well known for often improvising spoken word poetry passages while the band played live. Due to his wild personality and performances, he is regarded by critics and fans as one of the most iconic, charismatic, and pioneering frontmen in rock music history. Morrison was ranked number 47 on Rolling Stone's list of the "100 Greatest Singers of All Time", and number 22 on Classic Rock Magazine's "50 Greatest Singers In Rock". Morrison was known as the self-proclaimed "King of Orgasmic Rock".
