This piece is so absurdly difficult to find in nearly all respect, and I have no idea why! There seems to one complete recording available commercially (it is on Naxos, if you have access to that library).
Here is a recording of the third movement from youtube.
A Brief Overview of Schoenfield
Paul Schoenfield is a pianist, composer, and mathematics scholar at the University of Michigan, which his primary position at the University being on the composition faculty. His music is heavily influenced by Klezmer and Vaudeville styles. In short, his music is great fun!
A great deal of his music focuses on a comedic, lounge jazz piano part—usually premiered by Schoenfield himself—which pulls on the composer's time as a pianist for Murray's Steakhouse (this connection only seems to be documented between Cafe Music and the steakhouse, but if you listen to enough of his music in close proximity, one can easily pick up the same melodic fragment across about ten of his pieces).
A bit about the piece
This is such a fun piece! When it first starts, it sounds like one of the most dreary, contemporary pieces ever, but suddenly explodes into one of the most ruckus presentation of a concerto I have ever come across. What is really, REALLY nice about this piece is that it is void of pretension. It just is a fun, wonderful piece!
A great deal of this piece shares a great deal in common with Cafe Music (written in 1987) and his Trio (1990), and encapsulates the entertainment found in both these pieces, but amplifies it by the forces of a full orchestra!
Similarly to 1B, the publisher—this time Schirmer—is sitting on the rights to this piece and seems quite reluctant to let anyone get their hands on it. The difference this time is that Schirmer WILL rent the piece out for performance, but the humorously aggravating thing is that you cannot get a perusal score. This means you need to rent the piece without seeing any part of it, which means it almost never gets performed!
It really is unfortunate that such a neat and fun piece is under such tight restrictions by the publisher, but maybe if more people are aware of it, then more people will get it performed? I sure hope so!
