Sun Ra and His Arkestra - Jazz in Silhouette: X (X)

I would get a copy even though it's #jazz, because it's so well-regarded (eg, Penguin gave this a crown in every one of its editions); however, it was reissued in 1991 on CD in a first-generation transfer, and never remastered (except on a bloated, two-disc "expanded edition"). In that case, I usually will not buy original vinyl. Here again, I would make an exception given its stature, but vinyl copies are ridiculously expensive, so I'll do without.
