I dig the Mizell Bros' productions from that era.
And totally agree that Shorter's Etc. cover from the LT series is a classic and should've been the only cover it ever had. Perfect. Some of the others definitely work as well, and indeed better than the follow up edits.
Also, I thought these LT series covers were more under the influence of ECM rather than CTI in that they used a rather abstract photo that hinted/suggested a connection to the title and/or music contained and rarely if ever used shots of people. I guess maybe the cropping/border used on the LT series evoked some of the style of those earlier CTIs like Wave or some of the Wes Montgomery albums...? Using hind sight on this, it seems to me that those LT series covers help tell the story about the era they were released in a little better than the revisions, which do seem to muddy the BN story esp if like me one is coming to jazz at a much later time. I think maybe the only revised cover I like is Solid, but that's because it's a badass shot of Grant Green...but then the LT cover is good too.
