notes:

exactly same contents than on the other tape that I transferred, sound quality is about the same too, but this sounds slightly less clean than the other tape I got. Speed is also a bit slower than on the other tape, that I speedcorrected anyway, this source should sound terribly slow.

notes as they came with the files:
This is Recorder 2 of this underrated gig. Besides having Echoes [aka ROTSON] with the early lyrics, this tape's other big attraction is the version of Careful With That Axe, Eugene, which features some interesting and atypical playing from Nick Mason. It's also the first show of the band's Summer 1971 European tour, and the first time they performed ROTSON/Echoes outside of the U.K.
This cassette came to me back in 1997 as "5th or 6th gen", and I suspect that's about right. The original tape ran very, very slow, so I corrected the speed on playback using my cassette deck's pitch control. [Most of the show was something 9% slow, except for Embryo which was more like 7-8% off.] No EQ or digital processing of any kind was done.
Otherwise the quality is VG-, with all instruments present but a fairly distorted, compressed sound without much treble. Thus, for the most part Recorder 2 is inferior to Recorder 1, which is why it doesn't get around very much -- but Rec. 2 does have some pieces that aren't present on the other source, most notably the end of Saucerful. It's a very listenable tape, just not especially hi-fi.
Also, there are lots of edits on this recorder. I'm guessing these were probably made by the taper, who seems to have had little interest in any of the show's "non-musical" parts -- missing are the beginning of AHM, the middle of Cymbaline and ROTSON, and almost all of Saucerful. Plus Set the Controls isn't here either, and the end of FOS and beginning of Embryo were lost during [I'm guessing] a tape change.
There's another tape from Dusseldorf 1972 which has similar edits -- no Speak to Me, no Set the Controls, and no "seagull" section in Echoes -- which suggests that it may have been the same taper for both shows. [He must really not like Set the Controls!] Fortunately, in both cases we have alternate sources with the full show. Since the Dusseldorf 1972 master tape has supposedly surfaced, maybe we can hope to someday find the master tape for this Rec. 2 of 1971-06-04.
