Every summer, The Religion Guy luxuriates in a visit to western Massachusetts, known for outstanding theater troupes, art museums, a dance center, lectures and other cultural offerings all surrounding the Boston Symphony Orchestra’s incomparable Tanglewood music festival. (Disclosure: The Guy’s daughter is a BSO player.)

One BSO concert this July offered two George Gershwin piano features (not the over-programmed “Rhapsody in Blue”) and then “Petrushka” by Igor Stravinsky (1882–1971), a tuneful and witty ballet score about the life and loves of a classic Russian puppet. That got The Guy thinking about Stravinsky’s 1913 ballet in which musical art exploded into modernity, “The Rite of Spring: Pictures from Pagan Russia” (originally titled “The Great Sacrifice”).

His theme was the worship of pre-Christian Scythians adoring the earth, evoking their ancestors and then choosing a young maiden who danced herself to death as a sacrifice to the gods for a good harvest. The music is creepy, orgiastic, harmonically dissonant and rhythmically jagged. The premiere in Paris provoked a scandalous near-riot as astonished attendees audibly jeered, argued and tussled while the music proceeded.

That in turn brought to this listener’s mind the radical religious contrast between the “Rite” and another Stravinsky work The Guy heard at the Tanglewood debut of Andris Nelsons, who was later appointed Boston’s music director. Back in 1930 the orchestra marked its 50th anniversary by commissioning new works by the likes of Copland, Hanson, Hindemith, Honegger, Prokofiev and Respighi, and wanted Stravinsky to produce a conventional symphony.

Instead, he came up with a unique piece of sacred music, “Symphony of Psalms” for chorus and an orchestra minus violins and violas. This ranks as the 20th century’s finest composition on a biblical theme (any competitors?) and Time magazine proclaimed it one of the century’s three greatest classical compositions, alongside Copland’s “Appalachian Spring” and Ravel’s string quartet.
