There is a 1995 live Pink Floyd album and DVD called “Pulse.” It is excellent and there is no Roger Waters. It will also make you appreciate how vital Richard Wright was to the band. Of course, David Gilmour is awesome. Politically, he may not meet the Freerepublic purity test, but he is not an angry pinko like Waters.
Thank you. Gilmore is great, but Waters changed the history of rock.
