Published as a multimedia package, Andy Warhol's Index Book consisted of a book, pictures and a one-sided 7 inch picture flexi disc.
On the disc the Velvets are discussing the book itself, with their first album The Velvet Underground and Nico playing in the background.
As this point the album wasn't released yet, so this is first outing of the debut album.
Cale would later edit and reassemble Nico's spoken words from the flexi disc to use them for Ari Sleepy Too on the Dance Music album in 1998.
In March The Velvet Underground and Nico is finally released. Andy Warhol is credited as the producer, a promotion gimmick.
Warhol created the famous peelable banana cover.
The 2002 deluxe edition contains the mono and stereo mixes as well as a couple of solo Nico tracks. The 2012 45th anniversary deluxe edition contains Nico's Chelsea Girl album, the Norman Dolph acetate and a concert recorded at the Valleydale Ballroom in Columbus, Ohio, on November 4, 1966.
Records the mammoth drone piece Sun Blindness Music in October 1967.
The instumental piece is played on a Vox Continental organ. It is finally released in 2001 on the Sun Blindness Music album.
Cale plays viola, bass, guitar and piano on Nico's Chelsea Girl album. Winter Song written by Cale, Little Sister by Cale and Reed, and It Was a Pleasure Then by Nico, Cale and Reed.
The album was recorded quickly. Jackson Browne, who played guitar on the album, said that they had three days to complete the backing tracks. Cale would bemoan the rushing of thing as well:
"None of us had any patience, so it was very sloppy. We didn't have anybody telling us how to do things."
