Saw them at that time in concert - and as they were booked together with a Jeff Beck Group (can't remember the musicians) it was easy to pick the Hancock/Corea "retro" approach as a clear winner .....
Again hard to believe the wealth of funds the Stax imperium had at their disposal - and at the same time failed to build a roster of artist to succeed also in the 70's .... IMO one of the true historical tragedies of U.S music industry ....
The beauty of this status includes the suprise of finding discs (ideally BEFORE buying them a 2nd .... or 3rd time ....) you didn't remember having obtained before ....
