Dave Brubeck died today, just short of 92 years old. He was a plodding pianist and a less inventive composer than many obits are suggesting. (It was his alto saxophonist Paul Desmond who wrote the biggest hit "Take Five" in 5/4 time, and while Brubeck wrote many pieces in more exotic times still, they didn't swing or flow like Desmond's.) Still, Brubeck was a colossal figure of modern jazz in many ways.

Loudspeakers have been commercially available for nearly a century, yet those whose drive-units are mounted to baffles of intentionally limited width didn't appear in significant numbers until the 1980s. That seems a bit strange, given that the technology to transform large boards into smaller boards has existed since the Neolithic era.
