As Ubu Web notes:
"Counter Culture Chronicles has released on cassette a rare recording of Jack Kerouac at home in Northport, (Long Island), where he lived from 1958 to 1964. We hear Kerouac reading from his work while getting drunk and occasionally singing along with Frank Sinatra records that are being played in the background. Kerouac is clearly having a good time and takes the listener on a lucid deconstructionist trip, in which American popular culture is turned upside down and inside out. The recording covers the full ninety minutes the material. Have a seat and get filled to the brim with Kerouac's intoxicated mind. You won't get up again."
