Morgan’s synergy with Wayne Shorter is a highlight of this 1965 session; on “Trapped,” the two one-up each other with big entrances, leading up to a blistering trading-fours section.  Excellent Morgan originals form the album’s backbone: the brash “Yes I Can, No You Can’t,” the quirky blues “Speedball,” and the turbulent title track.  A set that overflows with melody and swagger.
