BTW, Roger Waters’ concert is one of the best I have ever been to. I was lucky enough to attend last week in Charlotte, and it was incredible.
Fleetwood Mac is good hanging out music too. Steve Miller too sometimes.
Anything by The Swans! Dark and enjoyable.
Okay, which albums get you stoned? (Not to death, of course)
While the two Floyd albums you mentioned are most worthy, and you did say anything else by them, I do feel that a few of the other Floyd albums that are quite effective for these purposes must be mentioned by name: Animals, Wish You Were Here and Works.
As far as newer albums, if you’re looking for something a little edgier, Alice in Chain’s “Dirt” CD is great from beginning to end. Another good newer one is** Ben Harper’s** latest CD,** “Burn to Shine.”**
(The Deadheads and Dave Matthews fanatics will be here any minute …)
Either Lou Reed’s METAL MACHINE MUSIC or the Simon Rattle/Binghamton recording of Mahler’s First…particularly the “landler” movement.
Hah! Fooled ya, Milo.
No, not “The Wall” (cuz it sux) nor even “Dark Side.” “Meddle” or “UmmaGumma.”
“Close to the Edge” by Yes.
“Astral Weeks” by Van.
Live Dead by the Grateful Dead
Susie Creamcheese by Frank Zappa
The Stealing Beauty Soundtrack
Bob Dylan - Blonde on Blonde
The Beatles - Sgt. Pepper
Happy Pot Smoking, kids!! 
ditto
Eat a Peach…Allman Brothers
“White Album”…The Beatles
Blood on the Tracks…Bob Dylan
Actually, the best record to listen to (stoned or not) is ANYTHING by John Prine. But I’m a bit biased.
Janis Joplin
Jimi Hendrix
The Doors
are all strong contenders, too.
Led Zeplin
Pink Floyd
Rush
Grateful Dead
Beatles
How bout movies to watch?
The Wall, Up in Smoke, The Wizard of Oz (Believe it, some pretty interesting stuff in there!)
Little Earthquakes (Tori Amos).
I have to second the vote for the aforementioned “Before and After Science” by Brian Eno.
I’d swear I listened to that album almost every day in college.
Ummmm…not that I was stoned or anything…
My drug days are long behind me, but here’s what i used to enjoy during my misspent youth.In addition to anything by Pink Floyd(Ummagumma, IMHO, being the trippiest selection), I would also nominate:
[list]
[li]Anything by King Crimson, although 21st Century Schizoid Man would be an excellent choice.[/li][li]Anything by Frank Zappa-Hot Rats or Uncle Meat being especially good[/li][li]Anything by Johann Sebastian Bach. Listening to the trills and cadenzas of baroque music really takes you into a different space when you trip. Trust me.[/li][li]Mozart’s Requiem The music, especially the Dies Irae, can make some intense space in your head.[/li]As far as videos, pretty much anything is good when you’re high, although I would say the Three Stooges, Bugs Bunny, and Yellow Submarine always worked for me.
Rush’s “2112,” particularly side one.
Jean-Mechel Jarre - Oxygene
