The music must change

It gets higher and higher

Smouldering like leaves in the sun

Then it bursts into fire

Its rhythm grows strong

It’s so new and so strange

Like bells in the clouds, then again

The music must change

-The Who, “The Music Must Change”

One of my favorite movies is “Oh Brother, Where Art Thou?,” a classic by the Coen brothers.  This film is a reworking of The Odyssey set in Depression-era Mississippi featuring runaway convicts from a work farm.  They seek a mythical hoard of cash but find instead a new and unexpected treasure in the music of the time, music that was so endearing that its early 20th century soundtrack became a best-selling CD.
