Set 01:
t01 - Jam #3
t02 - Jam #4
t03 - Jam #5
t04 - Jam #6
t05 - Jam #7

============================================================================

The first two jams on the transfer already circulate as Matrix, 12-16-1968.  The sources are 4529 (miller.neo_levo) and 97296 (boswell.smith).  The Knudsen versions are inferior to those that currently circulate and no serious attempt was made to remediate them.

Jam #1 (Getz jam)
- length: 32:49
- contains the same material that is on 4529 and 97296
- all three sources are uncut and end with applause, consistent with a performance venue such as the Matrix
- The knudsen tape runs 13-15% faster that the other two tapes (which have similar times of 37:51 and 38:18)
- I have no way of knowing which tape is pitched correctly
- Both the neo_levo and boswell sources are superior sounding

Jam #2 (Dryden jam)
- length: 44:48 (un-edited), 42:53 (edited)
- contains essentially the same material that is on 4529 and 97296
- the neo_levo source contains 3:07 minutes of tuneup that is not available on either the knudsen of boswell source.  It is apparent that noise reduction was applied
- the boswell source "slides" in at the start
- the knudsen source suffers from 2 major defects
--- there is a a discontinuity at 4:40 where two source are spliced together
----- approximately 2:15 of content is duplicated
----- the first source runs about 12% fast
----- the second source runs about 7% slow
--- there is a tape flip at 12:51 (un-edited timings)
-----there is approximately 20 secs of content missing
- both the the neo_levo and boswell sources are uncut

The remaining 5 jams which are contained in this file set all appear to be from a single source and are generally in good shape. However there are content gaps caused by a physical tape switch, a tape flip during the initial transfer to tape and seven dropouts of greater that 1 sec each in duration. All timings listed below are after any edits.

Jam #3 (34:55)
 00:00 fades in
 12:00 transition
 14:11 tape switch from tape 1B to tape 2A
 -- an unknown amount of music was lost
 -- the two sections were cross-faded (7.25 sec) to smooth the transition
 34:50 applause

Jam #4 (15:13)
 00:00 apparent clean start
 09:00 dropout: 1.513s, total deleted 2.385s
 09:49 dropout: 1.480s, total deleted 1.666s
 15:13 ends abrubtly - no applause

Jam #5 (13:25)
 00:00 apparent clean start
 -- there is an organ present for the first 20 sec
 06:46 the transfer source contained a fadeout / fadein section, apparently from the dubbing source
 -- there was 33 sec of duplicated content which was removed to provide a seamless transition
 11:59 dropout: 1.440s, total deleted 2.616s
 12:22 dropout: 1.417s, total deleted 4.973s
 12:37 dropout: 1.101s, total deleted 8.359s
 12:44 dropout: 1.413s, total deleted 4.329s
 13:06 dropout: 1.411s, total deleted 5.433s
 13:20 applause

Jam #6 (5:44)
 00:00	cuts in
 04:34 applause
 -- no apparent gap between jam #6 and jam #7

Jam #7 (10:14
 00:00 clean start
 06:53 woman's voice is heard very briefly
 10:10 ends with applause

Venue
-This is definitely not from the Jefferson Airplane House studio sessions documented in 12687 and generally attributed to 10-21-1968.  Those are close mic'ed studio recordings with lots of typical studio chatter
- Most jams are followed by audible applause that is consistent with a venue like the Matrix rather than the Jefferson Airplane House studio.
- it is possible that there was an afternoon jam session, followed by a performance jam session at the Matrix or a similar pubic location, in the evening

Date
- they played at the Greek Theatre on 10-20-1968 so they were in the bay area on the 21st
- based on the knudsen tapes, other than the tape label, there is no reason to believe that this content came from the recordings that generally circulate as 12-16.  As mentioned above, there are two distinct sources that make up the two jams from 12-16 and the content which provides the remaining five jams is generally consistent in quality and of better overall quality than the 12-16 sources
- It is unlikely that this content came from the 12-24 show because it is quite different, both in musicality and quality
- there is a recording that is likely from the Jefferson Airplane House studio from the same date, but with this performance occurring in the evening
- given this information, I kept the date provided on the tapes
