Forbidden Island was the third album by Martin Denny. The album was produced in March 1958 at the Liberty Studios in Hollywood, following the group's nine-month gig performing at Don the Beachcomber's Bora Bora Lounge in Hawaii. Forbidden Island was Denny's first album to be recorded and released after vibraphonist Arthur Lyman left the group to pursue his own solo career. The album includes four original compositions by Denny: "Cobra", "Exotica", "Primitiva", and "Forbidden Island".
