All PF albums are immortal, even I find Division Bell, which is a departure from the original "Pink Floyd Sound", to be excellent and musically satisfying but there is something very very especial about Wish You Were Here that can't be expressed in words. I don't know what state of mind PF were at the time they created & composed these songs but I consider this entire album to be the very best of PF creation, followed by DSOTM, off-coarse my personal opinion only.
My first PF album was Piper At the Gates of Dawn, followed by Wish You Were Here, DSOTM and others...all in the 80's and in Cassette tape format, since then I became so much engrossed that we started slowly owning them in various physical media lp, cd, vhs & dvd concerts, sacd over the time and now digital. Its a fun journey.
