Great little instrumental that has been a fave of mine for a long time!
The Marketts line up constantly changed, being made up of LA session musicians. Produced by Joe Saraceno, the Marketts are best known for their surf music but Saraceno took the band in whatever direction he thought would catch the buying public's ear.
This tune was originally titled Outer Limits based on the TV show but Rod Serling sued the Marketts for using the related four note theme without his permission. The title was changed to Out of Limits. It reached #3 on the Billboard charts in 1961.
The Marketts continued until 1977 but their last hit was in 1966.
