Thomas Conrad, Andrey Henkin

Jazz leads a hand-to-mouth existence. It was born in the red light district of New Orleans in the early 20th Century, and has never fully overcome its disreputable origins. Jazz lacks the support from governments, foundations, and rich donors that other, more decorous art forms enjoy. Jazz is too much of the street to be considered high culture, yet its audience is tiny compared to the masses who consume popular music. Pop stars like Taylor Swift perform in huge stadiums. Important jazz musicians play the Bar Bayeux in Brooklyn.

That title must have gotten your attention. Not the part about Art Pepper but the part about the CD. Nobody has anything good to say about the compact disc anymore. CD sales suck. Streaming and downloads rule the world. Vinyl (an album format that warps, scratches, and has to be flipped every 22 minutes) now outsells CDs.

But the CD still deserves a place in your heart. One reason: box sets. Many of them are worthy of coveting. For example, there is an amazing new project on the Omnivore label, Art Pepper's The Complete Maiden Voyage Recordings. It contains eight hours and 20 minutes of music on seven CDs. Collections that large do not lend themselves to LPs.
