Opera composer Puccini was a young man when he crafted this splendid work. Its text is the old-fashioned Roman Catholic Latin Mass. The title of the work derives from its longest component, the "Gloria." Youthful exuberance and optimism underlie the work.

Claudio Abbado’s youthful Beatle­cut marks the age of this film‚ still one of the better screen Barbieres if not absolutely the best. Jean­Pierre Ponnelle based it on his Scala stagings‚ but filmed it‚ as he always preferred‚ in studio and in lip­sync – more successfully than most. As a result‚ it looks and sounds very much fresher on DVD than contemp­orary videotapes.
