Doug Wildey, working for Hanna-Barbera, created a mature, stylish series that is as thrilling now as when it first aired in 1964. The series is notable for many reasons: the incredible voice over work, the well-rounded characters, exotic locations (drawing Calcutta costs as much as drawing a generic Southern California mountainside or cityscape), the imaginative stories featuring robot-spiders, yetis, mummies, and lizard men.
One of the best things about Jonny Quest is composer Hoyt Curtain's incredible jazz-soaked music. If you watched Saturday morning cartoons in the last 50 years, you know the Jonny Quest theme. The incidental music, which producers Hanna-Barbera often chopped up and tracked into other adventure cartoons they produced, is still thrilling.
One of my most favorite Curtain/Quest pieces of music, with those amazing drumbeats accentuated by horn blasts, can be found at the 1:20 to 2:26 mark below. Another fun piece starts at 4:20 to 5:52.
We can't talk about Quest music without mentioning the amazing, thrill a minute main title theme which just screams "adventure!".
