With its indelible Francis Wolff cover image of a pensive John Coltrane bathed in blue, freshly fired by Miles Davis but four months free of heroin, and its confident, accessible music that hints at the genius to come, Coltrane's Blue Train is a timeless jazz masterpiece. The saxophonist's only album as a leader for Blue Note, recorded before his triumphs at Atlantic Records—My Favorite Things and Coltrane Jazz—the boppy Blue Train, which, including the original mono and stereo pressings, had been issued 272 times, remains important for many reasons.

Maybe you've seen the widely circulated New Yorker cartoon: Two guys stand in front of a nicely drawn, tubed audio system, under which are shelves full of LPs. One guy says, "The two things that really drew me to vinyl were the expense and the inconvenience."

Most US shows experience a big drop in attendance on Sunday. Not at Audio Video 2022. Over 90% of Poland's residents may identify as Catholic, but that didn't stop thousands of them from visiting the Warsaw Show's three sites on the last day of the show. I still had to play musical chairs in many rooms before finally landing in or close to the sweet spot, and there were a few rooms that felt too crowded for comfort.

Audiophilia often leads the afflicted on a long journey, but no one need take that journey alone: Many audiophiles seek the company of like-minded people, on-line or in person, to exchange tips and advice, buy and sell gear, and share skills, fun, and musical experiences. And those who don't seek audiophile companionship? Perhaps they should.

"Focus on the unusual, the exotic," editor Jim Austin counseled by email. I didn't have to look very far. If Day One of the Audio Video Show 2022 in the huge Stadium was dominated by major brands, Day Two in the Radisson Sobieski Blu Hotel was filled with unusual speakers and electronics from small companies based in Poland and other European companies. Hardly any have a US presence, and many are searching for the right distributor to get them beyond the Polish border.

My trip to the Audio Video Show 2022 in Warsaw, Poland seems to have devolved into an unanticipated journey of protests. First, we almost delayed our pre-show mini-vacation in Paris—bless you, frequent flyer miles and friends—when, in the middle of a Workers' Strike, protestors were tear-gassed one block from the apartment of our hosts in the Montparnasse District. Then, on Day One of the show, I spent 45 minutes in the cold courting pneumonia as the shuttle bus between the Stadium and the Radisson Blu Sobieski Hotel was delayed due to a non-violent protest in the street near the start of the bus route.
