Mambo Jambo are not a surf band. They've got a sax heavy sound that seems to be aiming straight for the sound that record collectors have collectively dubbed "tittyshaker". There's also some definite jazz and exotica bits to it too. If, like me, they only recently walked into your mental library of instro groups, they've convenvienly put a good chunk of their library on bandcamp.
