General Notes:

Given the multiple sources available on the Llama, I decided to put the 
effort into editing a matrix of all three nights from this wonderful run 
at the Uptown. The Glassberg AUDs are very nice and full, standing on 
their own as excellent representative recordings.  The SBD sources of all
three nights have the reputation of being some of the crispiest boards
out there, and after a simple test on the Ship O' from the 3rd night I was
motivated to dive into editing land. The result is a worthwile listen, 
especially when you turn it up.

Timeline/Tracking Notes:

The only music that is missing is the encore from the SBD source.  
The transition between the disc 2 and 3 can be put together seemlessly.

Editing Notes:

- Pitch
Both sources were pitched differently, the AUD being the sharpest, 
and the SBD being the flatest.  I used the SBD as my master timeline 
and pitch referenced the AUD to it. The AUD on average had to be pitched
down about -.14 (14 cents) in the first set, and about -.03 (3 cents) in
the second set, to achieve pitch correction - 1.00 being 100 cents which 
is a semitone.  I did not reference A=440 as I did not desire to pitch 
adjust the SBD.  It is very close though to A=440.

- Synch
Because of the speed fluctuation within a given source, multiple edits
were performed to keep the sources synched.  Because the SBD was my
master pitch and time ref, the AUD was synched to the SBD (too many
edits to list).

- Sonic Quality/Matrix ratio
I did choose to employ a slight amount of limiting to the SBD (Waves L2)
to give it a slight amount of punch and presence. Conceptually,  all
I was trying to do here is to add some dimension to the SBD, which is 
pretty dry but very crisp, by using the ambience of the AUD. The result 
is a lively but clear recording, hopefully close to how it sounded at 
the show. If I had to guess the SBD/AUD ratio would be somewhere between 
3:1 and 4:1, leaning more towards the 4:1 end of things.

- Edits
The following are places where the SBD and AUD had holes or
incomplete coverage in reference to the final matrix timeline. 

SBD:
d1t01 (0:00:00 - 1:51:64) - missing (crowd)
d1t03>4 (4:30:20 - 0:07:49) - missing (mostly crowd)
d1t04 (8:51:64 - 10:00:16) - missing (crowd)
d1t05 (5:41:14 - 6:36:04) - missing (crowd)
d1t06 (8:31:42 - 08:39:06) - missing (crowd)
d1t07 (7:26:32 - 8:28:57) - missing (crowd)
d2t01 (0:00:00 - 2:22:15) - missing (crowd/tuning)
d2t05 (9:50:60 - 9:59:15) - missing (crowd)
d2t06 (2:08:07 - 2:17:60) - missing (tape flip)
d3t04>5 (10:57:09 - 0:07:12) - missing (tape flip)
d3t05 (8:18:61 - 9:44:72) - missing (crowd)
d3t06 (0:00:00 - 3:27:72) - missing all

AUD:
d1t07 (0:00:00 - 0:18:35) missing
d2t05 (6:53:16 - 7:00:41) missing (tape flip)

Note that alot of the missing elements from the SBD source are just 
crowd segments in between songs in the first set. The whole encore is 
missing from the SBD, but other than that, all of the music is intact.
