'Robert Letellier, as his readers would expect, has produced two substantial volumes, one on the Adolphe Adam operas the other on the Adolphe Adam ballets, totalling 733 pages. Thus, these two volumes, which also indicate the gifted writing ability of Adolphe Adam, embrace his entire output. However, each volume, one on opera, the other ballet, can be read as a standalone. Each is thoroughly researched with 10 categories of index, such as detailed accounts of singers and dancers who featured in his works, along with substantial references and bibliography. These books are beautifully produced with contemporary illustrations and fascinating, biographical details on Adam. However, for the serious student of these high arts, Letellier has maintained his reputation for thorough analysis. In short, these are a one stop shop for those who wish to know about Adolphe Adam and his creative output.'Dr Robert Gibson
