Almost Famous deleted scene:
10. Lester Bangs, Van Morrison, Astral Weeks
This is an assignment the I was forced to cut from the class, but a great experience nonetheless. One of the classic and best rock albums of the golden age of the album was Van Morrison’s Astral Weeks. It is lyrically very dark and jazz inflected. The experience is to listen to the album. It is a masterpiece of alienation that I compare to Catcher in the Rye—only set in Belfast. The bass line is magical.
The Wiki article has the interesting history of the album and a gloss of each song.
