This CD is often quite exciting, if a bit messy. Ornette Coleman (on alto, trumpet and violin) is heard with his "double quartet" Prime Time, which at the time was comprised of guitarists Bern Nix and Charlie Ellerbee, electric bassists Al MacDowell and Chris Walker, and drummers Denardo Coleman (who also plays some keyboards) and Calvin Weston. As if the ensembles are not dense and overcrowded enough, Jerry Garcia sits in on third guitar on three of the 11 Coleman originals. The music is frequently exciting, but will take several listens to absorb. Worth investigating.
