Steve & Maurice Oliver usually go by just "Rhythm Method" without a "The" prefix. However, there's another artist with the exact same name, who already have entries in MB. By coincidence, the only entries for "The Rhythm Method" happened to be for the right artist; I'm not sure whether all of the "Rhythm Method" entries are for the other one or not.
