Inner Core is the martial art created by the late Sensei Earl Squalls. Master Squalls taught children, particularly children of the inner city, many of
whom would not otherwise have had the means or resources to study martial arts. He stressed improvisation, and approached his art with the mind of a jazz musician, comfortably improvising at a moment's notice, and doing so
with considerable flair. Unfortunately, though his art was singularly unique in its techniques and approaches, much of it has been lost to time. In the 1980's, video cameras were very expensive commodities, certainly
beyond the means of a struggling martial arts instructor. Very little of what Sensei Squalls created has been preserved on film or video. Though he won many kumites, and kata competitions, we have no film clips of him
doing so, and know of none. Recognizing his contribution to martial arts, the four Inner Core empty hand kata have been incorporated into the Iron Crane School curriculum, as electives for those who chose to perform
them. We share them with you, as glimpses into the creativity of Earl Squalls, who, even today, inspires those who knew him well.
