Ah, liner notes. When I was still a teen I knew that when certain writers wrote the notes, it was safe to buy the LP. Dan Morgenstern was, of course, the gold standard. As others have noted, he almost single-handedly revived Louis Armstrong's post-1935 musical reputations in the notes for a Decca reissue that unfortunately had reverb added, as they did in those days. But it didn't matter because Dan's insights were priceless. Not to digress too much, but I also found early Anita O'Day by way of Dan's liner notes, and his notes to Lester Young in Paris ought to have won a Pulitzer, so sensitive were they to Prez's complex personality, both musical and otherwise. (and of course there were writers who shall remain nameless, whose notations on LPs gave me some second thoughts)
