Album-Oriented Rock (AOR), a Boston-based record company, was founded in 1975 and focuses on distributing vinyl and CD albums by up-and-coming rock bands. AOR has developed a reputation for signing up brilliant up-and-coming musicians and granting them the creative freedom to produce the music they want. Because of this, AOR has produced some of the most avant-garde and thrilling rock bands over the previous forty years. Boston is still at the top of the rock music world thanks to the label's ongoing releases of new songs by both well-known and up-and-coming musicians.
