Muddy Waters, "Hard Again", 33.3rpm, 180gram, produced by Johnny Winter, who also plays on the album, as well as James Cotton, Pine Top Perkins, and others.
Duke Ellington, "The Feeling Of Jazz", 45rpm, ORG Black Lion Records reissue. This double 45rpm album also came with a 33.3rpm record. Stellar sound and great music. The cover is a little different from what I found on the net, but only the position of the Black Lion Records symbol.
