In 2018 Jeff Knudsen donated his 5000+ cassette tape collection to www.shnflac.net.
The ensuing GEMS Lossless Legs production is releasing each of these tapes as raw transfers in digital format, one file per cassette side.

********** The GEMS Knudsen Tape Project  **********

In 2018, Jeff Knudsen bestowed his tape collection to the AZ GEMS
team for distribution and archiving. We have cherry picked some shows
and released them but have only scratched the surface. The process
of producing a complete and accurate mastered file set is time consuming:
select the show, compare to existing sources, adjust the tape deck,
transfer to digital, speed correct, master, aquire the source ID and
torrent. We realized we would never release most of collection using this
method.

As long as music is on tapes in a closet, it is useless. If it circulates
it is preserved for others and for the future. Rather than go through
the whole file set creation process, we transfer each tape or tape
side as a single digital file. A two tape concert consists either two big
audio files, 1 for each tape or 4 big audio files, one for each side of
the two cassettes.  We transfer professionally using the best gear and
a high quality Analog to Digital device. The Azimuth and Dolby settings
are correct. We release these files for everyone. We do not evaluate
the quality of the source, master it, or track it.

The Knudsen Tape Project is about sharing the tapes.

In each numbered release, along with the digital music files, we
include a photo of the tapes. The goal is to release as many of the
tapes as possible to the website www.shnflac.net.

We think the fruits of this project will become more interesting as time
passes. We believe that access to raw, properly transferred audio will
be of value to both present and future listeners, researchers and others.
Audio mastering technology is moving at breakneck speed. We can only imagine
the future technology that will be available. Having access to unmastered sources
could be invaluable.

HISTORY

The collection was started with a box of tapes Jeff Knudsen recieved
from his friend Dick Latvala in the late 70's. Dick was just a regular
guy in Pahoa, Hawaii and had not yet begun officially working with the
Greatful Dead. Over time, Jeff's collection grew. At that time, tapes were
currency and Jeff had gold. His collection increased to about 5000 coveted
tapes, via mail trades and all night copy-athons. Jeff shared them freely
and widely. If you had a soundboard tape in your collection years ago there
is a good chance it came from Jeff Knudsen.

WHAT CAN I DO WITH IT ?

Every release in this project is from a band that allows it's fans
to trade music non-commercially. We neither add or take away from that
permission. We only ask that you credit the Knudsen Tape Project if you
use the material. We ask nothing else of you and you do not need
to ask permission to use them. Since we ask only for source credit, we would
rather not hear complaints. Take what you need and leave the rest.

LINEAGE QUESTIONS

The notion of documenting lineage is a modern one, or simply one Jeff
did not entertain. We do not have lineage information on most of these
tapes. Any information we have will be in the photo of the tapes.
Some of the tapes sound absolutely fantastic. Others may remind
you of a tape you had long ago.

Now the rest is up to the community, with whom we have absolute faith
in the ability to discern.
