On April 30 I discussed the 50th anniversary of Blonde on Blonde so it is not necessary to repeat the discussion. On the same day the seminal Beach Boy album Pet Sounds was released. I didn't buy it when it was first released, but I bought a vinyl reissue several years later. I don't have a CD of it. Many consider it Brian Wilson's masterpiece. Part of the recent movie Love and Mercy described the making of Pet Sounds in 1966. There is a very detailed discussion of the album in the Wikipedia.
My favorite cut is "I Just Wasn't Made for These Times".
