Richard Pennycuick includes in the Naxos releases for July the following:

>IVES: Violin Sonatas 1-4

That set has already been out in the US for several months.  Indeed I
gave it a rave review when it appeared; it's the best I ever heard and
I've heard all but the Zukofsky/Kalish version (which is reputedly
superb).  Two completely unknown musicians are involved: Curt Thompson,
violin, and Rodney Waters, piano.

It just occurs to me that the announced release may be for hybrid SACD
version.  The earlier release is in plain-vanilla audio CD.
