I like CONTRASTS just fine. A bit loose, but more "together" than OF LOVE AND PEACE, at least to my ears. I like some tunes off of HEAVEN & EARTH better than others, but afaic, “The Cradle” is the most sublime of Young's ongoing series of organ/drums duets. Bottom line for me- if you just want the "highlight" of Young's BN career, you can skip these, but otherwie, there's enough meat there to justify getting them all in some form or fashion (which doesn't mean paying exhorbitant prices for the Mosaic).
The two Arista albums, otoh, are emminently ignorable. And ignoble. The music goes beyond being "dumbed down" into being outright dumb. Unequivically. No redeeming qualities whatsoever, not even in production values. Some pitiful shit.
The Muse side w/Chambers, otoh, is a delight. Be forwarned, however, hat Chambers plays piano on all but two cuts. So if you're expecting an album of blistering organ/drums duets, don't. But otherwise, grab this puppy and enjoy. Da' Bastids usually have "new reissue" copies (of what origin, I haven't a clue) of this on vinyl.
Not yet mentioned is LOVE CRY WANT. Incredible music, but defintiely not for the faint of heart. You've been warned.
