THE VAULTS / CD REISSUES : Jerry Lee Lewis, “Killer Country,” Mercury. *** 1/2

Long acknowledged as one of the great rock stylists, Lewis is also a marvelous country singer. In these 20 country tracks from the ‘60s and ‘70s, Lewis touches you with a heartbreak song, such as “Another Time, Another Place,” then amuses you with his vocal exaggeration in the bittersweet “Think About It, Darlin.’ ” A gem.
