The Roaratorio website mentions Sun Ra's "Other Strange Worlds" album on their News page, which should mean that they are about to release the LP.
Over at the Saturn newsgroup, gscala adds:
"early 2014 should see the release of a previously
unissued Sun Ra LP from 1966, entitled Other Strange Worlds. It draws from the same sessions as Strange
Strings -- perhaps the most singular recording in Ra's entire canon -- but
while that album featured a full size Arkestra, this one finds Ra exploring
similar territory with a small ensemble. "
