Downstairs in the casino, little remained of the MGM Grand Hotel’s former glory. In the early morning hours of 21 November 1980, a fire had broken out in the Las Vegas landmark, ripping through the lounge in an explosive wave that instantly killed everyone in the area. Bodies sat frozen in front of what had once been slot machines, now no more than blackened pillars jutting upward from a flow of melted slag along the floor. The room’s plastic and chrome-plated decor, it turned out, had been as much a facade as its promises of riches.
Fortunately, the Clark County Fire Department had responded immediately, and the blaze never spread beyond the first floor. From where David Demers and his fire investigation team stood on the 23rd floor, no one would have even felt the temperature rise. Why, then, were they surrounded by corpses?
As a choirmaster in 1870s Salzburg, Innocenz Achleitner often saw sheet music treated in a less-than-reverent manner. It might be scattered across a composer’s desk, crammed into vocalists’ folios, or even marred with personal notes about bowings or breath marks. Never before, however, had he seen it wrapped around vegetables.
Only about 80% of men at the time were literate enough to sign their own name, so it’s possible Achleitner’s greengrocer didn’t recognize what the marks on his packing material meant, especially since each page stretched roughly 80 centimeters tall and resembled something more like newsprint rather than a standard sheet of music. The choirmaster knew better, of course, and quickly convinced his grocer to hand them over.
Thus, by a coincidence of his shopping schedule, Achleitner happened to rescue the Missa Salisburgensis, or Salzburg Mass, known today to be the largest surviving composition from the Baroque era. It would come to be recognized as one of the most important historical works of music, and it would certainly cement its composer’s place as a master at the forefront of the era…if experts could figure out who wrote it.
