Follies (P.S. Classics, two CDs). The original-cast album of Eric Schaeffer’s standard-setting Kennedy Center revival of Stephen Sondheim’s great 1971 musical, which transferred to Broadway in the fall of 2011 and is now approaching the end of its run there (it will move to Los Angeles in May). More fully representative of the show than any previous recorded version, it preserves the magnificent performances of Danny Burstein and Jan Maxwell, and is essential listening for anyone who believes, as I do, that Follies is one of the permanent landmarks of postwar musical comedy (TT).
