I love Trouble in Mind, but both it and Full Force are extensions of things started in the late '70s - which is the problem with dong it by decade, music doesn't really divide up neatly like that. Full Force is part of a strong run on ECM for the AEC. 40 years later and Shepp is still doing duets with piano. Mirror, Mirror I'm not really familiar with, but tht could be said of pretty much any Joe Hen or Chick Corea after a certain point. I put something from either Trouble in Mind or Going Home on my blindfold test here and it got a pretty lukewarm and dismissive response, much to my disappointment.
