I've never heard this album, so I can't pass comment, though I frequently do an eBay search on what records people are buying from my saved sellers, and this seems to be selling like hotcakes.
But this makes me think of something I was musing over the other day. It's not so much that tastes change over time - it's more like during certain periods there are weird pre-conceived notions about what categories things belong in due to what is status quo and what is predominant. People use a lot of mental shortcuts because of what else is in the air at the time. Argh, I'm explaining this really poorly. I'll try to think of some examples of things where when it happened makes a critical difference in perception.
Okay, Robert Forster and Pam Grier were received well as love interests in the film, and as actors generally when Jackie Brown came out. But if that film came out in the actual 1970's, then the conventional wisdom about what kind of films those two actors did would probably influence critics to pan it.
Similarly, at least to my recollection, critics didn't used to gush over Bill Murray. His reputation's resurrection had to be put on hold until the memory of him being in 'that type of movie' (which weren't critics' favourites) was over.
So how it would work now is that an album which sounded right in the same field as, uhh, I dunno, whatever people have bought a lot of, say White Stripes or something, the tastemakers would be sniffy about - but if it were released ten years from now, they'd likely be more amenable.
This was a pretty shit opinion, and I regret taking so long to write it.
