Last year was the 50th anniversary of  The Beach Boys’ “Pet Sounds” –an album that startled the world with “God Only Knows,” “Wouldn’t It Be Nice,” and “Caroline No.”

Now, one year later, comes the highly anticipated documentary “The Beach  Boys: Making Pet Sounds,” airing tonight on Showtime at 8PM.

The film promises to “pull back the curtain” and reveal the process that resulted in an  album that, over the past half century, continues to grow in stature and music lore, ranking as Rolling Stone magazines #2 album OF ALL TIME, just behind The Beatles “Sgt. Pepper Lonely Hearts Club Band.”

This is a must see for music lovers of all ages and generations.

Here’s the trailer for tonight’s show.
