i always thought/seem to remember that that show was hard to listen to as it was such a bad recording?
In comparation with most of the North American shows or some European ones with good recording technology available (like Germany), it's bad, but if you compare it with the rest of the Spanish audience recordings, that most of them you can hear the audience screaming the songs and very low, DS playing at the very back, the Zaragoza 92 is like an excellent audience recording.
Only the Barcelona recordings have a decent sound from that tour. In Spain, in 1992, the technology to record shows in the fans's hands was a walkman with mic, and usually the mic was part of the walkman. I remember when listening to Zaragoza recording in 1992 thinking that it was a miracle that you can actually hear the band playing. Just play any of the Madrid recordings, for instance.
Being the very last DS concert, and in Spain, I stick to a 7/10 sound quality, being any of the Madrid ones 2/10.
