reactions to SMILE?

Too late by 35 years! I wonder how much greater the influence and interest would be if Brian had been able to finish this album before his problems peaked. It will probably be enjoyable, but unfortunately, it will be as if the album were transported 35 years into the future, and will undoubtedly not have the same impact that it would have had were the release not "shifted in time". I am hoping the reported "lost" extended version of "Heroes and Villains" has been found!

have you even heard it?

This isn't really the "lost" version, the songs were recently recorded. It's very good (IMO), but it's not a 30+ year old masterpiece, the songs are 30+ years old recorded recently with recent technology.

None the less, it's on my list to buy
