Why is David Lynch interviewing Eddie Vedder in Cameron Crowe’s new documentary to mark Pearl Jam’s 20-year anniversary? Why not?

Werner Herzog’s new movie about prison inmates on Death Row is called “Gazing into the Abyss,” and apparently consists largely of Herzog interviewing the inmates with this melodious cadence.

The trailer for Cameron Crowe’s new documentary to mark the 20-year anniversary of Pearl Jam, appropriately called “Pearl Jam Twenty,” begins with David Lynch, sounding for all the world like a dead ringer for Herzog, asking Eddie Vedder when music first started “being a thing” for him, whereupon Vedder gazes into the abyss of a speechless chasm and the trailer segues into old-school super-8 footage and voice-over reminiscences.

Cameron Crowe does great things with music. A teenage journalist for Rolling Stone, Crowe has always created impeccable soundtracks. He almost single-handedly introduced the world to Sigur Ros in “Vanilla Sky” and of course there’s the unforgettable “Almost Famous,” his last film before “Pearl Jam Twenty” to focus on music.

“Pearl Jam Twenty” airs on PBS October 21. Our DVRs are set—let’s hope “Pearl Jam Twenty” redeems Crowe for “Elizabethtown.”
