This truly unique collection of samples was recorded long time ago. I think it was released more than 10 years ago (in AKAI-samplers times). Now this library does not lose it's authentic but became more cheaper and more affordable. Size of the library is not very big (about 230 MB after extraction) and concentrated mostly on ethnic percussion sounds, loops, ambiences and voices. There are some musical stuff (like flutes and ocarina) available too but i think it's more suitable for effects but not for creating musical parts. This library will expand your sound palette with very rare and authentic Aztecs' sounds not available from any other resources (as i know).
