These are Buckingham Nicks demos c. 1970-1974.
They are called the "coffee plant demos" because Lindsey Buckingham and Stevie Nicks used to record
in the basement of Lindsey's father's coffee plant before they went to LA to get a record deal.
However, I feel that it is a bit of a misnomer because we know Sorcerer and Garbo were written after
the couple arrived in LA. Regardless, these are wonderful quality demos.
While some of these were released later by Stevie or Fleetwood Mac, the gem Without You,
the aptly named Cathouse Blues, and the quaint Goldfish and the Ladybug never made it off the shelf.
Authorship is not documented in those cases, but although Without You may have been co-written,
it is safe to say the others were penned by Stevie.
As you can see, the songs have more than one version. The only differences I can discern between
the versions are which instruments are brought forward in the mix, as indicated.
