Aladdin Records was a record company and label founded in Los Angeles in 1945 by brothers Eddie and Leo Mesner. It was originally called Philo Records before changing its name in 1946. Aladdin was known for jazz, rhythm and blues, and rock music. Some of these were issued on the company's short-lived Jazz: West imprint. Aladdin Records launched several subsidiary labels such as Score (1948), Intro (1950), 7-11 (1952), Ultra (1955), Jazz: West (1955), and Lamp (1956). In addition to Los Angeles, many Aladdin recordings were produced by Cosimo Matassa in New Orleans.
