Two separate vinyl sessions (EPs) will be issued by Resonance Records in connection with Record Store Day on April 19th. One contains the five(!) studio tracks recorded in 1955 by Epic. Only one of these has been issued on an old Columbia compilation.

The second release contains six live tracks recorded at the Turf Bar in 1956:

It looks like all this material (and maybe (likely?) more) will be issued later this year by Resonance on 2 CD/3 LP sets.
