Linda di Chamounix" provides a fascinating case study of Donizetti's habit of frequent rewriting, as it underwent three significant revisions in the year following its 1842 permiere. This critical edition of Linda di Chamounix, using sources that in some cases have never before been studied, allows performers and scholars to reconstruct all three versions. Appendixes include a contemporary orchestration of the stage band part and an early version of the first-act tenor aria which was replaced before the premiere and never performed.
