DMI recommended bill hamilton (yet i found his book a strange read in the 21st century) .... this may be from a similar era.

it's 20 minutes of audio.

May he r.i.p.  For those who don't know, he was the author of Zen In the Art of Motorcycle Maintenance and died Monday.

Thank you! Really enjoyed listening Pirsig's interview.
