I think Juanki is asking if there's anything on the 1999 release not on the LLL release, besides the second disc of the old docu-record. If I'm remembering right, everything on the 1999 is also on the LLL release, somewhere among the three discs. Can someone confirm?
Yes, everything that appears on the 1999 CD is on the La La Land set. The only difference is the Sony edition cuts off the ending of "Inner Workings". This edit is not duplicated on the La La Land set, but the take of the cue is the same.
The one thing "missing" from the La La Land set is a certain-mixed wind machine. Compared to the film, it's mixed very low. A minor quibble.
