Sir Lord Baltimore was a short lived 1970s American heavy metal band, from Brooklyn, NY. They released two albums on Mercury Records at the start of the seventies. A review of their first record, Kingdom Come, contained the first documented use of the term "heavy metal" to refer to a style of music. Both of their albums have since been re-released on a single compact disc. It is rumored that the band broke up after discovering that their contract had cut them out of all royalties from their first two albums.
