Clifford Thornton, Ketchaoua (side A)

1969's Ketchaoua leaps through many styles in a way that reminds me of the Art Ensemble of Chicago and also Archie Shepp in this era—Shepp appears on half of the album.  Side A contains two long tracks that feature large ensembles and a lot of simple, interweaving percussion.  Both tracks gradually evolve into brief periods of recognizable jazz styles before floating back into more abstract terrain.  The opening title track might be the least prominent appearance from drummer Sunny Murray, who blends into the massed percussion.  The two tracks on side B are opposite extremes, though both feature smaller groups.  "Brotherhood" draws from New York energy jazz, with Claude Delcloo's percussion prominent in the mix.  "Speak with Your Echo" ends the album with its sparsest arrangement, featuring only Thornton and two bassists.  The recording quality varies, with the large groups sounding better than "Brotherhood", where the explosive percussion reverberates awkwardly in a boxy room.  The simple packaging includes great photos of Thornton.
