March 21st 1975 Matrix in Led Zep Live Posted September 4, 2017 I listened to this over the weekend and was more or less blown away! The detail of a soundboard but the liveliness of an audience recording. There's a moment where the aud drops out during Black Dog and you can hear how sterile the sbd is on its own. My only complaint would be that on the mellotron songs, the guitar is drowned out. Particularly Kashmir, you can barely hear the guitar. Fantastic show. Especially Dazed and Confused, which has loads of inventive improvs, through the end of the show the band is on fire. But good vibes throughout. The only thing approaching a turkey is Trampled Underfoot, where they lose their place, but make up for it during the jam.
