Concord's upcoming releases include the following, according to a
new article on JazzTimes.com:

March 23
Rosemary Clooney: "Songs from the Classic Television Series"
(Intended to coincide, perhaps, with an upcoming PBS special on
Rosie that uses extensive clips from her 1956 TV series? Might
this include duets with her guests?)

April 27
Various Artists: "Live at Caesars Palace" (Neon Tonic)
Sammy Davis, Jr: "Live at Caesars Palace" (Neon Tonic)

This "Neon Tonic" imprint series was announced several years ago;
if memory serves it got tied up in some messy litigation and changed
hands once or twice? I think most of the material -- recorded without
the performers' knowledge? -- dates from the late 1960s and early
1970s? Jazz Times describes the various-artist disc as follows:

"Las Vegas ain't exactly the place you go to hear great music these
days, but back in the day, let me tell you... On April 27 Concord
will release 'Live at Caesars Palace,' a collection of never-before-
heard live performances by artists like Frank Sinatra, Keely Smith,
Lena Horne and even Duke Ellington, all recorded at the famous
casino."
