Here's an amazing new recording surfaced for the pleasure of all of us after 30 years!

Recorded on a Hitachi 290, using the microphone from the RCA YLS 15B portable reel to reel recorder. Original cassettes were transferred to a Mac DAW using a Nakamichi 480. The analog signal was first run through: a) a SAE 2800 parametric equalizer to bump the highs slightly; & b) a Phase Linear Autocorrelator to remove hiss. Lo Cut filter on Mackie 1402-VLZ used to remove grunge below 75 Hz (-18 db/octive).

Transferred to the Mac using a MOTU 896/Bias Peak. Bias Deck used to splice tape flips & even out volume levels. Bias Peak again used to transfer SDII files to WAV files for shn compression. xACT used to fix SBEs & encode to SHNs. This recording is one of literally dozens of concerts recorded by Joe Maloney in the late '60s - late '70s to be released to the live recording community. The bulk of the concerts recorded were in the Boston area, with some in Maine venues. - Jamie S.

After listening to this show, I decided to repair several of the annoying faults on DSOTM, mostly caused by tiny gaps in the music. I repaired Breathe (4.46), On the Run (8.29 & 9.38), Time (11.40 & 15.00), Us and Them (36.00), and made the tape-turn join better at the end of Brain Damage. Disc 2 indexing was all wrong, each track starting with the applause and tuning, so I changed it so that each track starts when the music starts, and having separate tracks for the tuning. No hiss reduction was required, just the careful edits to make the music flow much better. The quality is not very good to start with but soon improves in DSOTM, and it turns out to be a most enjoyable listen, with some nice different variations within DSOTM.
