"Sondheim Sings (Volume II: 1946-1960)," like the first volume, will include newly remastered demos from the composer-lyricist's private collection. Sondheim archivist Peter E. Jones, who serves on the board of PS Classics Inc., will again serve as album producer. Philip Chaffin, also a board member of PS Classics Inc., told Playbill.com, "Where the first volume had its share of rarities, the second volume is mostly rarities — material Sondheim wrote in college, or for early and often unproduced professional productions, or for the amusement of friends and colleagues in the 1950s. I consider myself as much a Sondheim fan as the next person, but most of this material was totally unfamiliar to me. It's an amazing overview of Sondheim's early writing career, and as a CD, it doesn't just feel like an extension of the first volume — this edition really has its own energy and feel, a kind of brash, youthful optimism that's very appealing."

Chaffin told Playbill.com he expects Volume II to include 20 tracks. A release date of Oct. 25 is expected.

As with the earlier "Sondheim Sings (Volume I: 1962-72)," a portion of the proceeds will go to Young Playwrights Inc., which Sondheim helped found and continues to champion.

Chaffin is also A&R Director of the Grammy-nominated record label PS Classics LLC, whose association with Stephen Sondheim includes Broadway cast albums of Assassins, The Frogs and Pacific Overtures.
