I am sitting in my living room streaming a Vivaldi recorder concerto from my computer through a miniBlink Bluetooth receiver, equipped with a Burr Brown PCM5102 24bit DAC, to a tube pre-amplifier and two Class A monoblock tube power amplifiers, ending up in a pair of bipolar tower loudspeakers that cheerfully reproduce a 16Hz low C pedal organ note: a thoroughly delicious amalgam of technology and the baroque.

If none of that made any sense, never fear: it is just the preamble to a joke I heard in Italy when visiting the house where Vivaldi lived. It’s this:

Vivaldi was the only composer who wrote the same concerto 400 times. An Italian told me that.
