Pink Floyd, well David Gilmour, is why I got into the whole music thing.
He is by far my favorite guitar player. And, Pink Floyd is my all time favorite band.
I like all of their stuff from the very early days up until the last.
Sometimes I might be "stuck" on the Wish You Were Here Album for 2-3 weeks.
And then that will change to any of the others. It is fascinating to see how different, yet similar a lot of the music is.
I am such a fan that I actually named my sons David and Nick. The wife wouldn't go for Roger or Richard for our third son. I guess you can't win them all.
Like mentioned above I really enjoy hearing a lot of the bootlegs.
There is actually a website that does Podcasts of live shows, mixed selections of the studio stuff
or just different versions and even demos.
(Not sure about this kind of link and the TOS, haven't read them in a while) but you can find the site searching for Floyd Podcasts. There are some really live shows on there, for sure.
