 The resulting album was backed by producer Lenny Waronker, who placed Parks' musical freedom over budgetary constraints.The album's sessions cost more than US$35,000 (exceeding US$ today), making it one of the most expensive pop albums ever recorded up to that time — in 1967, the typical budget for a pop studio album was about $10,000 (US$ today).The producers were able to make early use of an eight-track professional reel-to-reel recorder, which was used to mix second generation four-track tape that had been transferred from another four-track recording for overdubs.
