***Neonknight's Notes***
A new source to the community of this early DSOTM concert that I received on a pair of Mitsui discs from an experienced trading friend from the US about 7 years ago.

***Littlepieces' Mastering Notes***
This is a mono recording that was processed as two channel stereo. It has a phase shift that varies some but is generally about 16 samples for the 1st set and 5-16 samples for the 2nd set. So both channels were retained and manually aligned to improve the phasing.

The left channel gain was increased 3.0-3.9db in the Darkside set up to 2:48m into BD. From this point the sets SQ changes almost like a source change. Noise levels goes up and 9s seconds later the levels begin to rise and 35s later the left channel levels goes even higher. Output and hiss levels fluctuate in both channels but the left channel is notably more erratic. So I replaced the left channel with the right channel from 44:21m - 46:18m which is the last 80s of BD and the first 37s of Eclipse. No gain increase from 44:21m - 45:36m then multiple adjustments to both channels from +2.1db to +4.5db until the end of Darkside to help smooth the changes as much as possible without using any hiss reduction. The remaining volume fluctuations you hear in this segment are within the source as if the recording level is being changed. These cannot be addressed without segmenting further and reducing hiss to make the transitions transparent. No negative gain adjustments were made.

During the Darkside set BD has 1:37m more in the middle than rec1 because rec1 is missing music from around where the lyrics turn to how "the lunatic is in my head". There is also 50s of unaffected content not in rec1 prior to the SQ change at 2:48m into BD. It's also of note that this source's levels drop about 5s before Eclipse.

At the beginning of the 2nd set all of the audience and beginning of OoTD is louder than rest of the set, so I used the left channel as its output is lower, and replaced the right channel to avoid an obvious level difference or gain reduction. After this the left channel's gain was increased 1.5db up to 13:50m into Echoes. The 2nd set was phase shifted ~5 samples til 13:50m into Echoes when the shift increased to ~15 samples, or essentially the same as the 1st set and the left channel gain increase is no longer necessary. I realigned the channels again at this point to maintain proper phasing.

The speed was close enough most of the time, so I decided not to subject it to a SpC/resample.

The '3rd gen, 2nd source' CDR transfer of rec2 that seems to be related to this version runs about 2.5% faster, which accounts for this copy of the concert being ~2:40m longer. The levels and degree of phase shift and type of sound also differ so we can be confident that they are from different sources.
