This is the best Grateful Dead album cover by far, as I see it. In fact, I have never seen a better album cover than this one (although the first Black Sabath album cover comes darned close), not from any musician or musical group.
Of course, one could wish the album that came under that cover was better, I think it the worst Dead album to which I have ever listened. Then again, it's the Grateful Dead - in their heyday - and their music & song surely beats almost any crap rap, country bumpkin crooning (and you must realize I love Cash, Nelson & Jennings), 50s & 60s early rock n'roll, later rock, heavy metal (I love early Black Sabbath and Ozzy Osbourne), heavenly rock - just in case Elvis truly is alive, blues, rhythm & blues, bluegrass, swing, boogie-woogie, harmony, jazz, gospel, big band (although Glenn Miller & his band were pretty good) and classical music that is on the planet.
There is one musical work,that in my ears, beats them all - even anything by the Dead. That would be what I consider to be the closest thing to musical perfection ever on this earth & under or even in the heavens - Vivaldi's Four Seasons. With that one the music is truly a wonderfully masterful composition but all the various cover art I've seen for it sucks. It is just the opposite of the music versus the album cover for Blues for Allah.
All best,
