More orchestral works come from a September 1975 session with the 37-piece Abnuceals Emuukha Electric Symphony Orchestra, which was recorded at Royce Hall with conductor Michael Zearott.
The last recordings are live tracks including Tryin' to Grow a Chin from a February 1977 London show at the Hammersmith Odeon.

[26] Zappa announced Läther in a mid September 1977 interview, following a concert in San Diego, where he described it as his "current album".
Official documentation for the test pressing shows the project had a "Fixation Date" of 8/31/77 and a release scheduled for Halloween, October 31, 1977.

None of the four albums related to Läther were altered from the original CD issues, though new analog to digital transfers were made.
[2] While Zappa's notes from the tape boxes show a slightly different track listing, the 1996 CD version of Läther is musically identical to the 1977 test pressings.
Along with most of Zappa's material, a "mini-LP" CD edition was also released by Rykodisc in Japan, with the artwork reformatted to resemble the packaging of a vinyl album.
