I've never been shy about mentioning my love for the pre-Dark Side Pink Floyd. Their concert in Detroit in April 1972 was one of the most powerful music experiences of my university days. I saw them in 1973 at Maple Leaf Gardens and that too was a great concert but for me, the highlight of both shows was their earlier, more psychedelic material.
Fortunately, drummer Nick Mason is carrying the flame for Pink Floyd's earlier material with his Saucerful of Secrets band. A couple of years ago, I found a good quality video of one of his performances in Italy in 2023 and recently a new one popped up on YouTube. This concert is from the historic ampitheatre in Pompei, which was also the site of Pink Floyds 1972 concert that was made into an excellent film (now restored and making the rounds of better cinemas). This video is a fan production with multicam viideo, song titles and subtitles, and extra features. I'm not sure about the audio source, but it's quite listenable. Enjpy.
