Query: Give it time

Regardless of how you look at it, Astral Weeks has established a following of critical acclaim. While I can't say it's the best album of all time (I'm inclined to think Revolver), few can argue its importance and timelessness. Despite all the praise, Astral Weeks is not an accessible rock-and-roll album, like any of the Beatles work. It's not rock at all. It's nothing, yet it is everything. Don't expect to hear instantly memorable songs. Some tracks aren't even songs, just snippets of sound and a stream of consciousness. Like a fine wine from Bordeaux, this album needs lots of time. I must have listened to AW at least a dozen times before it started to click. It defies passive, background listening and you simply cannot understand this album unless you give it unwavering attention. If you don't like it at first, give it time. Give it lots of time, because there are few works in popular 20th century music that must have been made in heaven (think Davis's Kind of Blue).
