While some AMERICAN CLAVÉ recordings are available from select music retailers, as well as online sources like amazon.com, we suggest you try HDTracks, who try hard to carry everything, and Downtown Music Gallery (search by American Clave).

One other good web source: Museo Del Disco (note the little button leading to the English version of the site:). 

AMERICAN CLAVÉ is distributed in Japan by EastWorks Entertainment at ewe.co.jp.
