NEW RELEASES : In Brief

* * * Frank Morgan, “You Must Believe in Spring,” Antilles. The billing is a little misleading, since Morgan’s alto sax is not heard on five cuts; they are piano solos. On the others, Morgan joins each of the five pianists--Kenny Barron, Tommy Flanagan, Barry Harris, Roland Hanna, Hank Jones--for one or two duo numbers. This ultra-low-key set is not the one by which Morgan will be remembered years from now; however, no Morgan CD, especially in such elegant company, can be less than consistently listenable.
