let's see...

meddle by pink floyd (yes, also dark side -- also animals... and ummagumma/saucerful of secrets...)
abbey road by the beatniks (also sgt. pepper and revolver)
physical graffiti by led zep (also led zep II, led zep I, and... pretty much all the other ones...)
axis: bold as love, by jimi (also electric ladyland)
metallica: kill em all. (i know, that kinda stands out, doesn't it? that album was still their best because when it came out, it was clear they'd invented something new musically, and had apparently done prodigious quantities of coke and amphetamines to do it...)
also ac/dc: back in black. probably not worthy in retrospect but when i was fifteen it seemed like genius.
the police: synchronicity and ghost in the machine.
medeski martin and wood: friday afternoon in the universe.
and a band you never heard of called corduroy, with an album called "Dad Man Cat."

oh, and yes: the yes album, fragile, and close to the edge. all biggies, but for change-of-lifeness the yes album wins out.

i saw frizzle fry up there and have to add that, too. also sailing the seas of cheese.

did i mention RHCP, blood sugar sex magic? man, that was an album that made a big big splash.

and... edie brickell, shooting rubber bands at the stars. please don't beat me up! i love that album.

as long as i'm getting in touch with my feminine side -- joni mitchell's "court and spark" and "clouds."
